Can anyone tell me what this boxcar would be called: I found it on the MOPAC website and the details are thus: From/To: 786200-786399 DESIG: RBL CPY: 70 IL: 51'5" Doors: 10' PL CUFT 4543 LTWT: 74500 BLT: 68 I'm guessing that it's a 51'5" single plug door, but what does the RBL stand for? Also, does any know off-hand if there is a model manufacturer that makes undecs of this? I'd like to get some to model the one in the pic, since most MoPac boxcars are the standard boring brown. P.S. This one looks like it would be close (i.e., the rib sides) , except the doors are different (although the description says that they also come with single plug doors, which sounds like just what I need): http://www.walthers.com/exec/productinfo/480-1829 Thanks!
