Map Concept Art : Gravity Train Thread

Hi guys,
So been sketching and drawing for a while now, today spending about 4 hours on this work in progress. It is of a train station in a futuristic setting. The train inside is a gravity train (i.e. going underground through the earth etc inspired by total recall's idea). I'm about halfway through this the finished product should be out tomorrow .

Suggestion and comments welcome.
More concepts below

Part 2 of this concept is here! Added partially the main station at bottom and corrected lighting on the train.

Second instalment of this post is here.
I'm starting to think about some concepts for a game I may or may not make, this one here is for a Terran command and light support vehicle (Would have to have modifications done for that, i.e. armoured cockpit etc)

Any comment and suggestions welcome as usual.
Hugo
