What Era, Railroads, & Locomotives are you set on?

[Lester Perry]

I guess I am in the transition period of late 40s and early 50s. Mostly large steam Mikados are the smallest on main line service. 0-8-0 in the yard. Several GP 7 & 9, one SW900. I think it is pretty well known I model C&O. Coal & Freight both. Some where between 150 and 200 coal cars and probably around same number of freight. I have an operating layout which can keep seven operators working but so far four is the most I have had at one time. Also a short line with a 3 truck shay. I have 2 large coal mines and 3 small ones. I have a fairly large saw mill, 2 timber cutting areas to supply the mill. A lumber company, Fuel supply company, Furniture plant, large power plant that eats coal (35 car trains at a time). I have a warehouse transfer buiseness, team track. Oh yeah almost forgot the Gern facility which takes Box, tank and covered hoppers. I think that is all of it.
two 2-6-6-6, four 2-8-4, six 2-8-2, one 2-10-4.
