I was really wanting to make the T lines of Boston. But I need some help :P If any one has a server,and time to help I would love some help!

I want to make it at least kinda detailed and so Minecarts can ride in them, but also big tunnels for real-ish sized trains!
If possible I also want to make the stations them selves at the stop they should be at!

I realize this will be long and hard. But if you are willing, so am I.
