I just want to tell you that the cities in Train Fever grows.. so from 1960s, the game should allow for subway or light rail. Avenues came a lot with communism in Eastern Europe as communists looked at tram as a fast way to get workers to jobs.
Here is pictures of my cities from the same map:
The more you build in this game, the bigger the cities get. I have put trams as the most income source in the game. They transport people between cities since the start and just recently Ive added Highspeed TGV lines.
