Actually the 10-6's would be a better choice for N&W runthru. The PRR 10-6' cars along with the N&W 10-6's ran from New York to Hagerstown and down to Roanoke. Forget the train numbers but only saw it once since it stopped in my hometown in PA very early in the mornings. Remember it had 3 cars, one a baggage and 2 others (probably a coach and the 10-6 - June 2008 is their current carrot on a stick).

Bob, I already have 10-6s. N&W had only 3. They were used on Trains 1 & 2 (the valley train).
Since I model the mainline (the Pokey!) the through cars are for the Chicago connection, which for sure sometimes meant PRR P85 coaches. I sure as hell aint buying the main BL set for a 10-6!

(I might pick up one of the Walthers 10-6 in PRR though).
I think the sleeper from NY somehow ended up in little ole Williamson WV (connecting from the NY Train in Roanoke to the Pocahontas).
N&W rostered 20 of the Budd sleepers.
