Now the real question is - did Tonopah or NCO use them as sleepers?
Did Tonopah initially run them through on the C&C/N&C from the V&T at Moundhouse? Tonopah did not expect their connection to be standard gauged, so their initial heavy investment in narrow gauge equipment was understandable.
NCO was always looking for a bargain. While the buffet may have been handy, did they really need a sleeper? I've always heard it was an all-day run from end to end in narrow gauge days. Maybe the compartments were used as "first class" acommodations instead of a lounge/chair car?
