First, there's a timemaster mod.
Second, you're doing something wrong. I have a basic rail line at 1936 tops, fully functional railway by 1940s.
Third, IRL revenue steam routes were retired around 1970, so you have plenty of time to enjoy 'em. Also, there's very little point in retiring steam trains at all in this economy, because your coal reserves are bountiful and your slaves are free.
