Hello,
I have pak128 r1303 from SVN and Simutrans r6886 from SVN. Don't know if it is only pak bug or game bug. I click on railways and it creates end of choose signals on both sides, but if I click once more it stays on both sides (no change to only one side or another side if I click 2x, 3x,... too).
It is supposed to work like that.
But why? It can be only on one side or not?
It is available as a two-way signal only. Its only purpose is to "hide" station platform(s) from a choosesignal, so there is no use for it being directional (ie. be on one side or the other). If you need a station to be one-way only you can accomplish that by putting a signal on the other end of the platform. Maybe a screenshot of your game could help to see how you are trying to use the end of choosesignal.
