First, as far as I know the transition era (say 1945-1960) continues to be one of the most popular eras modeled. During that period there were 120 plus Class 1 railroads. One of these was the C&WC a 590 mile subsidiary of the Atlantic Coast Line RR. Cars of this railroad appeared nation wide, especially their box cars. Secondly, while most of their box cars were steel rebuilds of older double-sheathed cars they also fielded a small fleet of 1949 ACF cars exactly the same as ACL's O-26 class of box cars. These cars while fairly quickly repainted into the ACL after the 1959 merger, some retained C&WC lettering until the mid-1960's. Don't believe that too many of the steel rebuilds ever got ACL lettering. Do remember loading two C&WC lettered rebuilds in 1965-66 with material for the ACL. The steel rebuilds were in both single and double door. The latter 'til the end were marked "Automobile" 'tho all the loads I saw were lumber. Third, speaking strictly for myself I try every 4th or 5th purchase of a freight car to purchase either an uncommon road name or regularly lettered freight cars lettered numbered for a subsidiary, i.e. a Southern Pacific car for T&NO or Union Pacifc for OWR&N. And lastly, I apologize for the fact that I can't post photos - total computer illiteracy. p.s. - Depending on what became available, mark me either the first 5 or if more than 1 type/lettering style - the first 10.
