TU4 Finished

As usual it took far longer to get the TU4 model on the worktable and some work done. I last worked on the loco in August closing up the upper body and frame and getting a good fit with the lower frame part holding the bogies.

The tiny TU4-1135 is finished and photographed on a white background. 

One thing keeping me away from the task before me was probably the myriad of tiny etched metal parts to be fitted including steps, hand rails and door handles. During the Christmas holidays I bit the bullet and began drilling holes for the handrails, thinking that they were the largest parts and would provide me with some confidence if I succeedded with them. With some careful work I got the handrails removed from the etched fret and mounting them on the loco with AC glued went resonably trouble free. Footsteps under the cab doors were next and I finished off with the characteristic 'red banner' insignias on the bonnet tops. I decided to omit the door handles as they are probably a bit beyound my current abilities in H0 scale. 

The handrails were fitted in many different ways on TU4's during the years depending on model, owners' preferences and the wear and tear the locomotives were invariably victims of. Consequently there is no 'right' way of fitting e.g. the front handrails. Where I had drilled to mount the handrails I had to do some filling as my smallest drill was a bit oversize. This proces didn't work out to my full satisfaction and I'm getting a good supply of tiny drills for my next 1/87 scale project.  

Handrails are being installed - fiddly work that was seriously challenging my 1/19 scale accustomed eyes and fingers. No major disasters, but please don't look too closely on the finished model! 

K-Models has not included buffers in the kit, probably thinking that you'll fit some of your own choise. As my TU4 is going to be a static model I looked for some really good buffers of the standard Soviet type to fit. I found them in the RTM kit of the TU7. I plan to build the TU7 as an operating model and it will consequently have standard H0e couplings fitted, making its kit supplied buffers redundant. The buffers are 3D printed to a very high level of detail. Once I had removed the printing supports I was astonished to find that the chains actually worked! It's a testemony to the level that 3D printing has progressed to when you can have tiny coupling chains in 1/87 scale work directly out of the printer. The buffers were AC glued into holes drilled in the cut-outs in the loco's front.

When I had finished working on the body of the loco I added a scratch built centre mounted gearbox between the bogies. Two rectangular pieces of 2 mm thick plasticard and two circular shapes punched out of thinner plastic were glued together, sanded to shape and stuck on with AC-glue. It's nothing more than a coarse approximation built after prototype photos. I also added a few pipes for compressed air and hydraulic oil from thin wire. Not much of this will probably be viewable once the finished model is placed on an overgrown track on a future diorama.

Construction is finished and the model now awaits priming and painting.

After construction and sanding the worst glue marks, the window openings were masked and the loco primed with my usual 'Chaos Black' primer and painted green with red trim and orange handrails. I used Vallejo Air 71.134 'Imperial Japanese Army Medium Green' for the body's main green colour and 70.946 'Dark Red' for front skirts and frame trim. For the orange handrails I went with 70.910 'Orange Red' from Vallejo. From prototype images it seems that the roof is usually painted in the same colour as the body and so I left the roof in green and will rely on the weathering to make it stand out.

Halfway through air brushing the green I took this snapshot of the TU4 on my painting turntable from IKEA.

A few days later and details have been picked out in contrasting colours to convey a little of the characteristic colourfulness many TU4's locos displayed.

Before adding the kit supplied decals for TU4-1135 I gave the the decal locations a layer of gloss varnish to help the decals to lay down well on the surface. In 1/87 scale the decals are quite small and particularly the decal above the front coupling took some careful work to position more or less correctly. As usual I used Mr. Hobby decal solutions for best possible application of the small decals.

When the decals were in place I weathered the locomotive lightly. I'm building the TU4 as a non-operational loco that have been recently withdrawn from traffic. Hence no missing parts due to cannibalisation or heavy rust. I used my usual combination of oil washes, Vallejo weathering paints and dust spraying with the air brush. I restrained myself as much as possible as I figured I could easily overdo the weathering in this small scale. Once I was resonably satisfied with the weathering I added the kit glazing to the windows. As I had built a rudimentary instrument panel in the cab, the front glazing had to be slightly converted to fit. Fortunately I had done this in advance when access to the cab was easy. The side glazing had to be separated into two single pieces on both sides due to my way of fitting the cab handrails (the etchings were cut over length and protrudes into the cab), disturbing fitting of the original glazing. I glued the clear parts in place with 'Mikro Kristal Klear' that dries completly clear.  

Left side view of the TU4. Considering it has a length of roughly 9 cm I'm rather pleased with the result. This isn't exactly 1/19 large scale modelling!  

Right hand view of TU4 1135. The scratch built gearbox is just visible behind the air resevoirs.

With the TU4 finished I have reached the final milestone of an assembly process that I started in July 2024. I have been doing a lot of other modelling projects while working on the TU4. I have finished e.g. 3 skips and the Fowler loco in 1/19, completed basic landscaping on the layout as well as finishing a H0e MD54-2. Now I will turn my attention to a loco in 1/19 scale. No less daunting, but more in tune with what I usually model.

Most recently finished loco 'dumped' in the ballast with the next project on track! A rebuild of my Accucraft Baguley-Drewry is next on the list.

The 1/19 Baguley-Drewry locomotive is wider than the 1/87 TU4 is long. My eyes will be less tested on the Baguley project!

New HOe Wagon Arrived

Ice cooled reefers on Soviet narrow gauge? Yes, particularly the narrow gauge lines located in the agricultural regions of the Soviet Union were equipped with isolated refrigerator wagons. The 1/87 scale model of a Soviet narrow gauge reefer is part of a larger order that will arrive piecemal with irregular intervals from Ukraine. I was so satisfied with the quality of the two platform wagons that arrived in September that I had to have more!

Fresh out of its box. Another item for the Soviet narrow gauge collection.

The model is handbuilt in Ukraine by 'Miniland', the organisation that operate Ukraine's largest 1/87 scale model railway in Kyiv. The reefer is supplied in a tailor made wooden box with a laser cut outline of the reefer on the top of the lid and foam lining cut to fit tightly around the model. 

The prototype 'isothermic' wagon was built by the East German manufacturer 'VEB Waggonbau Bautzen' in 1954. As the term 'isotermic' reveal the wagons weren't exclusively for keeping their contents cool but rather at a constant temperature. In fact, the wagons were equipped with a heating stove and could consequently also keep the freight from freezing. Bautzen called them 'Kühlwagen' and in Ukraine they were known as 'Льодовик' literally 'glacier', so I guess the main role of the wagon would be to keep meat, fruit and vegetable cool in the warmer months of the year. The wagon was insulated with a layer of 20 cm thick insulation material and could carry 2 tons of ice in compartements to keep the freight cold.

As everything on the Soviet narrow gauge railways the reefer wagons were quite large with a carrying capacity of 15 t. Via thermometers the temperature could be monitored from the outside. Ladders on the ends gave access to roof boards that were used when filling the ice compartments.

Works photograph from Bautzen showing a light coloured 'Kühlwagen' - cooling wagon. The wagons were seen in light grey (perhaps white?), green and brown colours. 

A preserved reefer in the railway museum in Anykščiai at the 'Aukštaitijos' 750 mm narrow gauge railway from Panevėžys to Rubikiai in Lithuania. The thickness of the doors are evident. The wagon has lost many fittings, including the end ladders.

The wagon is priced at 116 € and that is only a little more than a pretty standard H0 Danish passenger car  - and the reefer comes with a nice storage box rather than a flimsy one made from cardboard. Being very good quallity, a rare prototype and handbuilt by a craftsman/woman, I don't consider the price high.

Brake cylinder, back up air tank and piping. Hard to believe this is 1/87 scale and hand made. 

Good, clean decal application. Paint has been applied without faults. Nice work.

Roof running boards around one of the openings for filling the internal ice boxes. Notice the drain leading water over the wagon's end.

Delivery was swift and from ordering to delivery a mere 6 days passed. Quite hard to understand how that is doable from a country being the victim of a Russian invasion and suffering devastating air attacks on its cities almost every night. All the more reason to appreciate the careful work laid in the detailed model!

Soviet Bogie Platform Wagons

In my continued proces of building up a collection of Soviet narrow gauge rolling stock, two platform wagons arrived today by mail. Quite unusual for such rather rare prototypes they are out of the box delivered finished and ready for service (even if I don't have a layout to use them on).

 

Two new platform wagons unpacked and photographed in the garden with a MD-54-2 and a piece of mining machinery as load.

The protoype for the models is a simple steel framed platform wagon with sheet metal floor and cast steel 'american-style' bogies and central couplings. Pockets for stakes to enable transport of wood etc. are placed on the outside frames. Several types of platform wagons were built by Demikhovo Engineering Works (DMZ) with some of them having very low sides and some strengthening beams across the load area - probably for transporting logs. The Demikhovo Engineering Works (Демиховский Машиностроительный Завод, ДМЗ) in Demikhovo near Moscow was founded in the Soviet Union in the 1930's building machines for the peat industry including bogie hoppers by the thousands. Today the company is the Russian Federation's main producer of EMU's. 

Drawing and data sheet of almost identical platform wagon built by DMZ. It's fun that the gauge is stated as being 1520 mm - clearly a mistake!

Works photograph of a platform wagon from Demikhovo.

The wagons are handbuilt in Ukraine by the Ukrainian 'Miniland' model railway organisation that is best known for operating Ukraine's largest 1/87 scale model railway in Kyiv. They are not what I would consider cheap, but the quality/price ratio is well balanced and I already have more models on order. Packaging on arrival from Kyiv is top quality, and once cardboard box and bubblewrap was removed I had a tailor-made lasercut wooden box in my hands. The box will help protect the models from all but the most viscious mishandling.

The contents laser engraved on the lid of the wooden box supplied as a safe home for the models.

With the lid off the wagons can be seen fitting into the foam lining of the box. Thin plastic wrapping makes it easy to extract the models.

The models correspond to available drawings of Demikhovo platform wagons and both are assembled with care, bearing no visible marks from glue, solder or files etc. The wagons are equipped with full underside detail like air tank, pipes and brake rodding. Paint is well applied, probably by air brush, and the lettering is clear and the wagons carry individual numbers and appropriate data.

As an extremely utilitarian design the Demikhovo platform wagons weren't the kind of rolling stock anyone took a particularly interest in. Consequently most images show prototype wagons heavily weathered and worn. As long as all eight wheels touched the rails and the couplings pointed in the right direction all seems to have been fine. I look forward to add weathering to the models in the future. For the time being they will stay in their nice box.

Platform wagon loaded with two substantial concrete elements. This particular wagon seems to have been light grey in a distant past. Surely an inspiration for my future weathering work on the two models.

Huge Skip Progressing

During some busy weeks I have none the less managed to work on the unbreaked 1/10 scale steel skip from Feldbahnfactory. Basic assembly was accomplished during a weekend in the cottage and priming, painting and weathering is almost done by now. I plan to add final touches once I have assembled the braked skip. That will make it easier to get both skips finished with the same look and faster, too. 

Almost finished DIN standard steel skip in 1/10 scale photographed in the spring sunshine in the garden.

I have never built a kit in such a large scale in laser cut wood. I didn't experience any problems during assembly and the instructions are top quality and easy to follow. I didn't make any alterations in the assembly sequence which I usually do. Probably not too many ways to assemble a skip, I suppose?

I assembled the kit while in the cottage with just basic modelling tools and standard white PVA glue. I was a little sceptical with the kit's prolific use of layering parts to achieve mass in e.g. frame, wheels and the skip rests. In reality, once finished, the layering is only noticable in a few places. I'm sure that with basic filler and sanding the problem could be avoided, but I wanted to build the kit in the most simple fashion. 

Frames and wheel sets united. A nice detail is that the bracket for a round wooden beam for braking is included in the kit. A detail not present in many model skips.

Almost assenbled skip put together as a test with the cottage surroundings in the background. If assembled very carefully the kit will not look bad unpainted.

I had no trouble removing most of the parts from the frets. Only on one fret (the one with the skip body parts) it seemed like the cutting could have been done better. Nothing that hampered the build, but slightly annoying in an otherwise perfectly produced kit. The few and quite small attachment points on the parts are easily sanded away. On some parts I sanded the edges a little to avoid a square look. I did that e.g. to the edges of the skip's frame and the coupling chains. This is an area where a full laser cut kit will always come out a bit inferior to a kit that mix materials to achieve more prototype shapes. 

The rivets on the skip are represented with very shallow cuts marking out the rivet. In this large scale a real raised rivet would be much better, but it's one of the features laser cutting can't produce. Adding rivets can't be too difficult in 1/10 scale and if I aimed for a more detailed look of my two 1/10 skips I would probably take that approach. On the other hand the Feldbahnfactory kit is super simple to put together. In my view it has a good level of detail for its simplicity of assembly.

End view of the painted skip on the short track panel included with the kit. I have numbered the skip with roman numerals, on this end with a white pencil, a method I have also used in 1/19 scale.

Here is one of the places where the layering of kit parts are visible. Not too obvious and I will disguise it with some lost gravel and dust from the loading proces. This end of the skip has a fancy logo from a Ukrainian 750 mm narrow gauge railway in the western part of the country around Borzhava, Боршавська вузькоколійна залізниця.

The wood grain isn't particularly noticably on most parts. In this close-up you can see traces of layering on the skip body rests and some wood grain marks on the safety handle.

How the wooden parts would look once painted had me worried intially. Sometimes wood behave crazy when painted and no amount of sanding will make it look like anything but crazy wood. The wood used in this kit works well with standard rattle can spray can paint. I used a mix of my usual black primer from Games Workshop and the Beltoni texture rust paint, that I have used previously on my 1/19 scale bogie timber bolsters. The texture in the rust paint help create as slightly uneven surface on the skip, an effect I further enhanced with sprinkled on genuine rust dust from a prototype skip. Using ground up real rust is part of my 'Famous for nothing weathering method'. Further spot painting was done with an air brush and different dark greys. Initial weathering consists of an overall wash with heavily diluted rust coloured oil paint. I will be adding more weathering when I finish the braked skip. Weathering them together will help make them look like coming from the same industry.

Coupling chains during painting. Heavy work with files produced quite nice rounded chain links.

As a conclusion I feel that most of my reservations with the kit was put to shame. Where I suspected the kit to let me down (wood texture, round parts, layering etc.) it was either insignificant or easily avoidable with a little work. If you are looking for some impressively large skip models to display the Feldbahnfactory models are easily assempled and will look good on your shelf, mantlepiece or as a nerdy office display. My braked skip kit is on the Easter holiday modelling programme as it is a large kit that lends itself to outdoor modelling in the cottage. 

The Feldbahnfactory skip is great little (large) kit of the widespread steel DIN skip. It provides a resonably cheap and easy way of getting that impressive skip train on a shelf or in a museum's display case.

MD-54-2 in 1/87 Scale

The mailman rang the doorbell and delivered a package from Ukraine with yet another 750 mm gauge Soviet locomotive model in 1/87 scale. The company K-Model from Kyiv has a large range of H0 scale model cars and vehicles. Added to that is a small number of 750 mm narrow gauge models in the same scale. I have shopped in Kyiv before and am in the proces of  building (now and then, at least) their TU-4 loco.

Two 1/87 scale MD54-2 locos right out of the parcel from Ukraine.

MD54-2 locomotives were built by the Istinsk Machine Building Plant (200 km southeast of Moscow) between 1953-1962. The type was designed as a replacement for older small narrow gauge locos for 600 and 750 mm gauge of Soviet manufacture and a wide array of locos acquired as war booty and reparations. A riveted frame with two axles on elliptical springs carried what was basically the upper body and mechanical parts from the DT54 tracked tractor. A total of 1817 MD54-2 locomotives were built (a small number by Soviet standards). A very similar loco was the MKD-35 built primarily for the smallest industrial railways with 600 mm gauge where regauging to 750 mm wasn't economically viable. 

A lot can be said about the MD54-2 but it's not first in line for a design award!

The model is delivered assembled, painted and fitted with glazing in the windows. The model is tiny, measuring only 5.3 cm in length and 2 cm in width. Each loco is accompanied by a skip model that looks somewhat proportionally challenged. I bought two locos and the two skips are going straight to my box of spareparts.

The model is 3D printed, is unmotorized and fitted with metal wheelsets. Despite being resonably well protected by bubble wrap and a sturdy cardboard box some headlights and an exhaust pipe had broken off during transit. I could retrieve the broken off parts from the wrapping and they will be kept safe until I begin working on the models.

Image from Ebay showing the MD54-2 model with the accompanying skip. At least I can source two central buffers for a future project.

MD54-2 1027 preserved at the Pereslav railway museum in the small town Talitsy in Yaroslavl Oblast, Russia. The colours could indicate that this is the actual prototype for the K-Models model.

The MD54-2 models are now packed safely away in a small cardboard box as they are not high on my list of modelling tasks. I have 1/19 projects that are far more important and I have begun assembling the new 1/10 scale skips as well. The most important thing is that I now have two MD54-2 locos in my collection. You never know how long small manufacturers survive in a niche market. 

Summer Modelling TU4

Dedicated followers of this blog will probably recognise the checkered table cloth. A sure sign that I'm vacationing in the cottage and holiday modelling. And that's just what I am! For a change I have brought a 1/87 scale kit to assemble to the best of my abilities. The small size is perfect for bringing away from the house, but the tiny parts are quite challenging. Nevertheless I press on and hope to have the kit more or less finished once my vacation is over.

Assembly of the K-Model's TU4 in resin with etched metal details. I forgot my travel size cutting mat, but in the cottage we're never short of a scrap of wood to use as a substitute. 

The TU4-kit comes without instructions for assembly. Not the biggest of problems as the number of parts is pretty small. It is probably the placing of the tiny etched metal parts where the missing instructions will annoy me the most. The kit supplies parts for a static loco only and I'm keeping the model that way. No experiments with tiny H0e mechanisms this time!

TU4 bogies with wheels and gauge adjusting shims fitted. A small casting fault on one flange probably won't be noticed once the model is fitted on a small diorama. 

I began by sanding away flash on the parts from the frame and bogies. I then AC-glued the front skirts to the frame part and test fitted a pair of wheels on the stub axles on a bogie casting. The gauge didn't quite match 9 mm so I drilled and cut four shims to add on the axle subs. As I was away from my stash of all sorts of plasticcard pieces I couldn't find a piece thin enough to add on both sides of the bogie. The obtain a decent fit in the track, the shims were placed crosswise on each bogie. Once the bogie sides were superglued on bogie assembly incl. wheels I drilled chassis and bogies for M2 bolts for safe and flexible mounting. This will allow for realistically posing the loco on both curved and straight H0e track.

Two models from K-Model next to each other. The TU4 is still mostly unglued and only assembled to test how the major parts fit. The TU4 is 88 mm over the frame ends, while the PD-1 is 75 mm over the buffers. My 1/19 Baguley-Drewry is wider than the TU4 is long. Must get a photo of them together!

After removing flash from the upper body I closed the openings from cab to the two bonnets and installed very a rudimentary instrument panel. It's built from plasticcard and I'm not claiming any accuracy as it's all built from pictures showing only part of the construction. Not much will be seen through the windows anyway. The cab interior was primed and then brush painted a medium grey.

As I had the black primer out, I primed the bogies as well and brush painted them dark grey with wheels being given a layer of rust colour.

It's beginning to look like a TU4. It looks like I will have to build a gear box protruding down between the air tanks.

I have been working out the remaining assembly and painting process and next is some major work on the body. The upper body will be glued to the frames. A range of small parts must be attached, mostly photo etched parts of a frightening small size. Very interesting work coming up!

TU7 and Closed Goods Wagons in 1/87 Scale

The packages from Ukraine keeps arriving, bringing my supplies for a little diorama of a mining location in Eastern Europe to new levels. This time I shopped at Retro Trains Models in Kryvyi Rih in the Donetsk region. The order took no more than a week and a half to travel from Eastern Ukraine to Denmark. Parcels from the UK often have longer shipping time.

Two goods wagons, a TU7 and a Tomytec drive unit have arrived on my work table.

RTM produce high quality resin kits of 1520 mm standard gauge Ukrainian locomotives (that would be broad gauge to us) as well as an expanding series of narrow gauge loco and rolling stock. The level of detail is quite high and the TU7 kit has more parts than my 1/19 Lister (even when counting all the parts I added myself). I think that illustrates the level of detail possible in the RTM kits. If I will manage to apply all those very tiny parts neatly remains to be seen!

Data sheet of a TU7A. Despite being in Russian, most railway enthusiasts should be able to interpret the info and see that this is not a tiny narrow gauge locomotive. 

The TU7 type was developed in 1971/72 at the Kambarka Engineering Works to replace the company's older 750 mm gauge locomotive types TU4 and TU2. The type is still in production at Kambarka, although in an updated version (TU7A) introduced in 1986. The production of TU7 reached well over 3000 units and several hundred were exported to e.g. Cuba and Vietnam. The TU7 was designed for use on on gauges ranging from 750 mm to 1435 mm and standard gauge. Cuba received standard gauge TU7s while the Vietnamese ones were 1000 mm. Like the TU4s at Western European heritage lines, a TU7 has also found its way west, as the 603 mm gauged Brecon Mountain Railway in Wales acquired TU7-1698 from Latvia in 2010. The TU7 is a versatile construction fitting in on railways with gauges varying from 600 to 1435 mm gauge!

The RTM TU7 is a resin kit with a high level of detail and designed to fit on the Tomytec TM-21. While the recently bought TU4 will be a static model the Tomytec drive unit will enable me to build a functional locomotive. 

A simple design with single end cab. Fault free casting with no flash at all. Test assembly of a few major parts shows a perfect fit. 

Well packed kit with an impressive decal sheet.

To accompany the TU4 and TU7 a few wagons was in order and I selected two closed goods wagons built by Demikhovo Engineering Works (Демиховский Машиностроительный Завод, ДМЗ) in Demikhov near Moscow. The plant was founded in the Soviet Union in the 1930's building machines for the peat industri including bogie hoppers by the thousands. Today the company is Russia's main producer of EMU's. The prototype goods wagons seems to be a type built from 1965 and into the 1980's with a load capacity of 20 t. From photographs and a single drawing the RTM kit looks very close to prototype. As the TU7 kit the wagons have lots of fiddly parts and a high level of detail.  

The RTM kit's upper body test fitted on the combined frame and floor part. A rather long 750 mm gauge goods wagon, but still a quite small model (compared to what I usually build).

The sudden investment i H0e models of Soviet prototypes is not a sign of a change of scale, but merely meant to be an enjoyable side show allowing me to model another field of interest in a much smaller scale. The Nystrup Gravel project moves on in its usual slow pace hampered by the usual time limiting factors of life (not that I'm complaining). This week I have been working (10 minutes or something) on track detailing before adding vegetation and ballast. 

Close-up of a Peco point partly rebuilt with wooden sleepers. As I rebuilt the two points, the frog sections kept their plastic sleepers. On one of the points the sleepers have now received a layer of medium grey paint. The upper right part has also had a thin wash of raw umber oil paint. Further weathering will hopefully help the plastic sleepers to blend into the rest of the hand built track on the layout.
