The US President's Bulletproof Railcar

Before Air Force One, this is how POTUS got around the country. Check out the armor. Also not mentioned in the video is on the approach to NY Grand Central Terminal there is a special spur and station for the Waldorf Austoria Hotel where this car would park and which Roosevelt would use instead of Grand Central Terminal on his visits to New York City, he would exit the Hotel via a special exit in his special car and form a motorcade. Much higher security than using the train station.
