I'm looking for some information concerning the doors used on New York
Central boxcars from Lot 773-B. These cars were numbered NYC 168000-
168999, built in 1949. Both Superior and Youngstown doors seem to have
been used; NYC 168111 had a Superior door, while NYC 168658 and 168737
had Youngstown doors. Does anyone know how many cars recieved which
doors, and the breakdown in car numbers?
