(Because the 1000 Character Limit Saves Space, which I'm not good at...)

I'm amazed at how much detail went into this. Basically everything works (and that includes f*cking plumbing! On a train!!)
You can also extinguish the fire and/or turn off the electricity for xtra spoopy effexts n stuff

Biggest problems I have:

-Train Lag
Train is a bit laggy when you first throw it into gear, but once it gets going everything runs fine. FPS seem to be highest when the train isn't moving, which isn't a surprise.

-Don't Stand There!
Never spawn foot soldiers with the train at top speed. The game will absolutely hate you for doing this.

-Bon Fire
Bon fire at spawn is a little annoying, as you try to hurry along and no-clip through it and you instantly die. (I mean I don't know what I expected, but that said the "death radius" is rather large)

-We Lack Technology to Open Doors
Combine cannot board the train unless you literally open a door for them. Kind of ruins the whole "ambush" thing that is implied when they attack, but no map is perfect I suppose. Another problem is that unless the Combine physically board the train, it is impossible for them to penetrate the idiots inside it (unless you open the side-doors on the armory).

-Not enough breakable sh!t
I admit I complain about this in 95% of maps I have ever played, and to be honest I think you might completely murder Garry's Mod if you try to fit in anything breakable. (except maybe a few crates...)

-Textures are Meh
I personally am not a huge fan of the textures. Then again, a lot of maps of this type I don't really like because of the textures, so I guess it's something that can't really be fixed or avoided...

Overall, fantastic map, the amount of details is incredible, and the AI's are surprisingly intelegent (unlike my spelling).
