W0A0A-W0A0B func_trackautochange Issues

I'm trying to make a map similar to the "c0a0" - "c0a0e" maps from vanilla Half-Life 1.

I want this map, "w0a0b", to start with the tram moving downwards on a func_trackautochange entity, with a func_train elevator below the tram/trackchange combo. After that, it should continue along normally.

But neither entity wants to move. It obviously starts to because after the levelchange from "w0a0a" (which is the only way this setup can work (semi-)correctly, so start from that map), I can hear the sounds of the train stopping and the elevator moving.

I've included as much as I can in the .zip to (maybe) be able to fix the problem if someone figures out what's going wrong.

EDIT: ^ Disregard the above ^. Problem fixed. w0a0a and w0a0b merged.
