MDC/Roundhouse 50' Boxcar

["thommack <mack@c...>" <mack@c...>]

Does anyone know how well the MDC/Roundhouse HO scale 50' single door 
box car (Roundhouse Part 1190) matches the Q prototype? It is painted 
in an odd green scheme since they were apparently leased by/to 
General American Transportation. They have the CB&Q reporting marks, 
but do not say "Burlington" on the car. The CB&Q car number is 23506.

Any info on the use of these cars would also be helpful.

Thanks,

Tom Mack
