Trains seems to be overshooting signals and platforms by a little. No problems with path routing though. Just a little graphical issues. Trains seems to smacking into each other, if the signals are placed right before the cross-track.
Unless things have changed in Standard recently, this problem is not confined to Experimental; I am not quite sure whether this is a problem with the graphical alignment in Pak128.Britain or an issue with the code in Standard or some combination of the both. I have moved the topic to Development and Bug Reports for the time being, but no doubt it can be moved further if that is not the correct board.
