Good enough approximation. I don't know how accurate the BLE original is, but to me it seems a steel sheathed wooden car on a steel underframe, ca 1915 built.
This is a shorter car compared to the picture of #200 the OP posted, so I suggest a numbering range of 817-824, per this WM listing:
http://www.alphabetroute.com/wm/rosterp ... erUnit.pdf, to have it fit in the imaginary roster.
Pictures of WM passenger cars in revenue service are very hard to come by, since WM never was a real passenger mainline of name and fame.
For smaller passenger trains that protected local and secondary services, a combine or a baggage-RPO car would make a nice addition. The BLE DLC has a shorter baggage car already that could be repainted.
Obviously, a good set of generic heavyweight passenger cars with repainting templates will be a very welcome addition.
- full length (77'-80') for mainline expresses, shorter cars for branch line, commuter and local services;
- 4 wheel and 6 wheel trucks under the day coaches and combines, 6 wheel trucks under the full bagage, mail, coaches, Pullman sleepers, diners and observation cars. Both plain bearing and roller bearing variations on the modernized cars;
- clerestory roofs, original or rebuilt with full or partial air conditioning ducts, ice and battery boxes, etc as child objects? Nodes to the shape files require scripting and entries in the scenario editor, which is perhaps undesirable?
- marker lights to denote the End of Train!
