The Iowa traction railway is a 10.4 Mile electrified freight railroad located in the United States. It mostly switches Tankers and hoppers for various different businesses along the line. It’s very unique as it’s one of the only electric freight railways and the only electric traction railway in the US. It would make a great TSW route as there’s lots of switching to do, plus every time you change direction you have to lower one pole and raise the other. Here is a video of the steeplecab locomotives in action.
