General changes and bug fixes:
Train bells have been added, and you can stand on the train now.
Inactive red spawns are now disabled
Adjusted clipping and lighting for various areas.
C windows are now solid
Changed some geometry so it is clear you can't get onto certain areas now
A:
Red wasn't using the high ground to the left of the point that much. I've added some ammo and added a ramp up to incentivise holding there, while making the blue side of the bridge forward hold much more open...
