FVM Announcement CSX Canstock box cars # 504011, 504034, 504045, 504061

Requesting some information on these cars. Does anyone know the build dates of these cars ? Are any of them still on the active roster today ?
Thanks for you assistance.

I know there are prototype photos out there online... some are posted with the information that you're looking for.

I'd start with RailcarPhotos.com and rrpicturearchives.net .

 

Loads of info starting on page 13: http://www.borhs.org/sentinel/sentinel2010Q20510.pdf

 

Thanks for your responses. The photo sites had some nice shots, but no builders information. Point353, thanks for pointing me to the B&O article. This had everything I was looking for and more !
Regards.
