Conrail cars between CSX & NS

[angelob6660]

When Conrail was spilt up between CSX and Norfolk Southern there freight cars separated between them.

Now I was wondering does CSX only own Conrail equipment with NYC reporting marks and NS only CR markings.

How do I spot the difference between other Conrail equipment.

PRR was the reporting mark for NS rolling stock and NYC for CSX.

I never see PRR reporting marks on freight cars, but I did it on ex-CR diesels.

You are correct...Conrail equipment that went to CSX was relettered NYC, without being renumbered.  This relettering began well before the actual split in 1999.  It was pretty close to 3/7 of the equipment that went to CSX.  They may have inherited another reporting mark or two as well (I'm thinking that all remaining CNJ cars went to CSX), but I can't find my documentation on that at the moment.

Freight cars for NS retained their CR reporting marks, or whichever historic reporting marks they had at the time of the merger (so you might see some PRR, PC, EL, etc., cars around yet).  No freight cars were relettered PRR from other reporting marks as a result of the merger.

NS later began to reletter and renumber its ex-Cons into the NS series (usually, if not always, into the 600000 series), and to give it a classification code that showed its history (a NS box car is class B-nnn; an ex-CR box car would be class BP-nnn, for example).

CSX's ex-CR cars will remain lettered NYC, though their numbers may change as the result of rebuildings.  I've seen this on hoppers rebuilt for aggregate service, hi-cube box cars, and gondolas enlarged for automotive "fluff".

Conrail owned all the "marks" from all the predecessor roads.  When the split was done, CSX got fewer cars than NS, so the CSX cars were the ones that were all remarked.  A decision was made to give CSX the NYC mark and let NS keep the rest, including CR.  Prior to "day one" all the cars going to CSX were remarked "NYC" and the NS cars all kept their existing marks:  CR, PC, EL, RDG, etc.
