PC: NYC express boxcars as work equipment?

[Jerry Jordak <jer@xxxxxxxxxxxxx>]

Hi everyone,

Last night while browsing the shelves at the LHS, I found one of these 
Walthers express boxcars that was rebuilt from an old WWII troop sleeper:

I thought it was an interesting model, but my layout has no passenger 
service. (Not by my choice, the PRR killed it off several years 
earlier.) However, I know that a lot of old passenger equipment ended up 
in MOW service.

Which begs my question: were these troop sleepers ever used in MOW 
service on Penn Central? Or were they even still around by the time of 
the merger? Just curious if anyone has any information on these cars. 
I'd figure I'd ask before I spend $20 on one. :)

Thanks,
