Good addition to the 2vs2 map pack. To make it 3vs3 its a bit too little and to make it 2vs2 its a little to big, so ...
There is more Stalingrad feeling and gameplay than on the actual Stalingrad map. I would keep the old map but rename Railroad Station one into "
Stalingrad Railroad station"
We have then a third Stalingrad map
Minor improvements:

Can you clear the entrance to the hall? Vehicles have a hard work to get through (especially hard for PE). My panthers got killed because they couldnt move.
The crater to the left might be removed too.

Same goes for the opposite side. Pls delete those small hills and move the VP a little bit to the right

Thats what i told you about today. If you straighten the tracks up the most right one would be next to the big crane. (there are 5 tracks to straighten i think)

I think you can delete that little building

. Looks very robust but i didnt think the soviets did build like this.

There can actually drive vehicles through. Very irritating for the comp. If you made it a bit more narrow only Infantry can enter it. Like it was intended i think.
Who has spotted the little guy i painted?
