When my modules are set up my primary visual concern is to disguise the narrow gap between them. I have tried to hide the gaps with grass and shrubbery. But having grass every 80 cm will end up being far too obvious.
My newest module - the one with the bridge over a small stream - is for the next few years the end of the line. The left end of the module is designed to enable a connection to be made to the only other established industrial railway in the scale range 1:35-1:32 in Denmark. My friend's modules are not of the exact same profile as mine and to help disguise that the module is finished off with a wooden fence, grass and shrubbery.
My 1:35 fence is supposed to be surrounding the bakelite factory 'Bankes Bakelit'. The fence is made from wood and quite simple. Just like a real fence. The lettering on the fence is hand painted after the letters were marked out in pencil. Not as difficult as I thought.
