I REALLLY like the fact that the railways is right there and I fully plan to take advantage of this.
Like you mentioned earlier--maybe for transportation of food--I thought that would be really neat--also somehow connecting the actual structure to the railways through a bridge over the railways --because i mean even thought the railways is still used-I don't feel like it should be something that people should be wary of or avoid because it "may" be dangerous--like I want to draw people into that space that is so vacant and unoccupied--not sure how to do this yet.

and concept model--hmmmm--still have no clue. a little nervous about that.

I'm trying to think of what to say about about your conceptual model--
have you thought of materials? yet, how are you going to build it?
instead of something being broken for prosthesis--have you thought of somthing being propped up maybe? I dunno--thats all i can of right now lol
I'll post more once i have more to say :D
