Okay, I'm finally done with my entry. So this little guy here is in the track control room, and he accidentally died. Cardiac arrest maybe? The autopsy will tell.
Of course, when the track controller dies at work, bad things happen. Remember it's early 20th century, they didn't have automation then, did they?

After a traumatic crash experience (that happens during setup time, and it's way too dynamic to show on screenshots, so run the .bsp to have a good idea of what I'm talking about), the BLU team emerges from their luckily unharmed passenger cars.

It's designed as an A/D spawn room, due to the setup time restriction. There are four exits, two on each side - one on ground level, and one accessible through a tunnel and a catwalk system. Rather than the usual pillar-supported stuff, I went for a suspended version.
