I would like to see a UK route or a US Route set in the late 1800s like the Central Pacific Railroad set in 1884 a year before the Southern Pacific absorbed the railroad. The Metropolitan Railways in 1868 The Virginia and Truckee Railroad set in 1898 What are your route suggestions set in the late 1800s?
How about central railroad of New Jersey Allentown, PA to Clinton ,NJ. Germany Prussian Railways Kaliningrad section. When Kaliningrad was Under control of Germany pre 1945.
