steam locomotives are a part of historical engineering of the late 1880s- the 1960s and shows advancement in technology and successes of the late 20th century. it fascinates me to even see a steam locomotive in this game, at first I thought it was similar to some American engines, but clearly I noticed that the engine in the game doesn't have a cow catcher on the front of the buffers and the smoke stack is a lot smaller compared to any American steam locomotives.
