awesome, very impressive 
I think you are right about how Borawian Railways could have developed up to date: A possible development past 1950, when my scenario ends could have been as follows: In the late 1930's the trunklines Harwan/Luacha to Gathoma was electrified with 15.000 KW, 16,3 Hz in an attemt to increase capacity, and from that time, only a few new steam locomotives were built. The first diesels appeared in the early 1950's, but until the 1970's a few steam engines still lingered on operating freight trains on secondary lines. A contrast to the trunk line to Gathoma is the (important) secondary line between Luacha to Moa, being a scenic train ride with lots of tunnels crossing many fertile valleys. This line is run by railcars (passengers) and diesels (freight). During the period 1965-75 many secondary lines were closed and The Borawian network became somewhat trunkated. After many years of decay, steps were taken to upgrade the surving system in the years 1995-2005.
