does the 'engine' at least CLOSELY match the rolling stock? ... engine=Atlas N B30-7 CSX
Let's look at this with a little more
useful information this time if you're looking to keep it mostly accurate. In 1992 CSX rostered eighty-one GE B30-7 diesels, built from 1978-81; they were originally purchased by Seaboard Coast Line and Chesapeake & Ohio. Atlas has offered them in two paint schemes,
blue and gray and
"YN2". According to
rosters on Bullsheet most were repainted to YN2 by 1995. You didn't specify which paint scheme your unit sports, however.
If you want to be accurate you'll want to find cars that were common for the era you're trying to portray. By the time CSX was created, however, railroads had changed drastically from deregulation. The majority of freight moved in 50' or larger freight cars. Railroads had begun the shift to shipper-owned rolling stock for many commodities. The exact mix of cars you choose should be dictated by what industries you intend to see on your layout, the era its set it, and its geographic location. (From memory CSX's four axle GE fleet was mostly used in the South, probably on intermodal trains early in their life and on mixed freights later.)
What would go best with a CSX B30-7?
Kaolin tank cars, for sure, and
boxcars to handle forest products. From the economy Trainman line there are a number of appropriate choices including the
ACF boxcar,
ACF covered hopper, and
90-ton hopper. A
modern CSX caboose would also be appropriate.
If the south isn't your thing, the B30s did wander north on occasion so there's no reason you couldn't model any portion of the CSX system with it. In which case just about any modern freight car can be used, just try to avoid cars with 1) roofwalks, 2) friction-bearing trucks, and 3) railroads that were gone before the 1980s. Have fun shopping!
