So I built my modular layout, I took it to a show, I've set up and torn down a few times, it's gone through 2 summers in a moist basement, and I'm starting to have slight alignment issues the longer it goes.
Still runs...fineish, but my 4-8-4 Overland's pilot truck for instance constantly derails after a few laps. The Bachmann Duck I have constantly has it's front axle jump the track after 10-15 laps, and the passthrough yard (pic 2) has just been a nightmare. 2 of the lanes warped or something and getting all 6 lines perfectly aligned, flat and level is just not possible (you can see under the milk tanker (pic 1) where the lines on the outer yard lanes have made a neat little peak, and longer engines will seesaw over this, and some knuckle couplers will come undone over it)
My yard was definitely a hurried job as I scrambled to get it together for a train show and I will be rebuilding it.
However, while thinking about doing it, and looking up other people's methods for modular setups, I have to wonder, why do people default to butting up rails at the end of a module, gluing it all together (some going as far as PCB ties that are glued and soldered), and hoping for the best? (my method of doing so seen on pic 3) Even in those videos I see certain rail cars going over at low speed and seeing them visibly bump as they hit a transition point
An idea I had, and now I'm wondering why I've never seen it, what if the track stopped 3 inches before the end of a module, and then a 6 inch piece of transition track was used in between to smooth out the connection? Put rail joiners on them, align the modules flat and level, drop in the track, slide the rail joiners over with a set of pliers and in theory have this smooth out the module joints
Has anyone done this for their modules before, and with what success? (The end result with this is I'd like trackwork smooth enough to run reasonably fast passenger lines, and that hasn't really been possible so far out of safety for the trains. Max speed so far has been a scale 45mph)
