B&O RDG CNJ Coal Hopper Roster

Folks,

A while back, I ran across a spreadsheet or large chart on the Internet that listed all sorts of data for hoppers used by the B&O, the RDG and the CNJ. Chief among that data were class, car numbers and capacity.For whatever reason, I can’t relocate the thing for love or money.

I thought it might have been a product of a group connected to CNJ heritage, but that didn’t lead me anywhere either. I could use the information contained in it, so any help is appreciated.

Thanks in advance!
