I think escaping from trap is intentional and also I will list few bugs that resulted from Cream Tea's Extremely Perfect Mapping:
-Cubemaps aren't build, so purple checkermarks on the wood of trap 2 exit.
-You can still do the credits room secret when motivator coming, all you have to do is wait until motivator activates train, when train goes away, hurry to the rail room and wait, then done.
-The russian roulette's spectator side's window is making you look to the glitched view like you are looking at a nodraw, I assume decompile broken it and you didn't fixed it.
-Make doors disappear in map start only active when side selected.
-Instead of making the train active when motivator passes, just put a trigger_hurt covering the back area.
What a mess...
