MNCX *METRO-NORTH COMMUTER RAILROAD. An interesting but false report involving MNCX has been popping
up on the news. MNCX baggage car 002 supposedly was found on a unused track
under the Waldorf Astoria Hotel in New York City. It was reported on the
Discovery Channel and Fox Television News that the car was used to carry the
Pierce Arrow limosine owned by President Franklin D. Roosevelt. Because he could
not walk, FDR supposedly rode in the limo inside this car to the Waldorf Astoria
when travelling to New York. The limo would be driven from the car and onto an
elevator which would lift it to the hotel at street level. The car was
armour plated, had exceptionally heavy trucks for a super-smooth ride, and had
bullet proof windows. In truth, 002 is nothing more than an ordinary baggage car
which at one time had been used as a tool car for a wreck train. Trains magazine,
April 2012 issue, carried a feature article about the car.
