Railway post office car #95 was one of seven of its class built in 1914 by the Pullman Company for the ICRR and is thought to be the only survivor in its original state. Usually six postal employees, not railroad workers, were on board to retrieve, sort, and deliver the mail at scheduled stops. Mail was loaded and unloaded in sacks through sliding doors, but when there was no scheduled stop, mail to be picked up was placed in a sack on a mail crane next to the tracks and retrieved with a mail hook. Mail to be delivered was simply kicked out the door as the train passed through. These RPO cars operated only on express or through trains.
