[0.15.37] Train collisions on automatic paths

[Jon8RFC]

I'm not sure if this is related to the weird path finding issue I've seen bug reports for, or if it's related to this bug: viewtopic.php?f=29&t=44108

I noticed that some trains that had crashed into each other. I'm not sure if they crashed because I removed and placed new tracks far away from this spot, or if it was the other path-finding issue, because the time between me placing tracks and noticing it was probably a solid half hour, or more.

Here's the save I made when I spotted the collision, on the multiplayer server:

Attached is my log.

There have been a large number of train pathfinding corrections in 0.16,
So this is probably fixed

If not, please make a new bug report
