Train self collision logic issue

There is an issue with the trains' self collision logic. I have a scenario where it thinks it will collide with itself, but it isn't anywhere near long enough to do so. I think the notes said that it reserves some extra space, but this is like double the train's length.

Save attached. The station that does it is the "Glass prod" station.

Also, for some reason trains don't see the bottom most switch as a valid path, which is really what's causing this issue in my layout anyway.

save.save

Files not imported: save.save

I need to test this with 0.7.3 since it should be fixed...will try to remember to do so asap

This seems to be fixed for this scenario, the loop correctly takes the train's length into account
