Great Northern Railway proposal
I've seen and ridden the line to Port Random. I'm a bit disappointed at how it doesn't neatly integrate with the RT system, not even within the Viktoria station itself. Add that with the Steamer Line station next door and Negusville Station further away, that makes it three lines connecting to the North Line in such close proximity - and two of which are ad hoc and so close to each other as to make travel actually slower and cumbersome.
My proposal is to connect the Port Random Line from Viktoria to the North Branch Line in Negusville that leads to Cowville, forming a continuous line from Port Random to Cowville and beyond (to the extreme northeast). This will be the Great Northern Railway. Feel free to offer alternate names though.
I hope to receive approval and cooperation of the owners of Port Random Line and both Viktoria and Steamer Line Stations to make this work.
