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.
