I agree about the ACL cars. I recall riding to New York from Baltimore on an ACL train in about 1953. Normally passengers getting on at Baltimore and points north were not permitted to ride the trains from south of DC but the Congressional, which was supposed to leave Baltimore at 7:42, was late and passengers were permitted to ride the train from the south. It had an ACL and an REA express reefers on it. The ACL car was the striped scheme.
I have an actual paint scheme chart from the ACL for this car. It is about 2 X 3 foot.
The B&O did not have anything like this car. What they did have were 50 foot single door baggage cars and troop cars that were made into express cars.
