| This RPO 
                heavyweight passenger car is green with white lettering and runs 
                on 6-wheel passenger trucks. Built in 1914 by the Laconia Car 
                Company, they were equipped to sort and catalogue mail en-route, 
                with mail bag storage racks and sorting tables. While these cars 
                did not have the recognizable wide baggage doors of some RPOs, 
                they did still have mail slots for public drop-off of mail parcels 
                directly into the car. |
