I know there's a train yard in Harwood, Portland, so that could probably be converted into an end-of-the-line station. Or maybe that construction site in Staunton Island can be completed, along with a train station built onto it?
I think that yard is connected with docks. And there are alot of problems to connect them
It's kinda connected to the port, but the other side of it, you can make a bridge going over the water
