The outer track is longer than the inner track, but the rail lengths and sleeper spacings remain the same. So the position of the joints and sleepers would get increasingly out of step as you move along the curve. Here you can see that on a sharp curve the joints get out of step very quickly, starting from being in line on the left: 2_130141_060000000.png On long straight tracks it would be possible to align the rail joints and spacings, but there is no reason to do that and it would be a lot of extra work -- it's likely that shortened rails would be needed on one track or the other at the start of the straight. It would be necessary to align the joints because the sleeper spacings are not constant within a rail length, being closed up towards the joints at each end of the rail. regards, Martin. posted: 13 Oct 2017 09 ...
