Very nice, thanks for posting. I'm thinking that the first private car is a former SAL Solarium car? If so, I didn't know that any of these beautiful cars remained. With the SAL's (and ACL's too) cars in operation north of Washington, DC to New York City under PRR wire, there was no clearance for domes.
The first car is ex-Seaboard. The next two belong to Northern Sky Rail Charters. The last car is "Caritas", which is well known in the rail charter world. I believe it is now owned by the Friends of the 261 group?
