Question for train experts: With all that armouring protecting it from threats from the side, how would it protect the occupants if someone tampered with the rails or blew up the train from below?,(reply>), I do see this happen in the movies. I also have a simply answer, escape hatch,(reply>), The floor of the car is also armored, as is the roof.  I used to be a member of the Museum when I still lived down there.  I was one of three people who rode the car as security in 1990 when the car travelled to Ogdensburg NY for the 50th anniversary of the signing of the Ogdensburg Agreement. The car is VERY comfortable to ride in.,(reply>), I think the answer is surprisingly "pedestrian" they either checked the tracks before the train would come through (back in the day "regular" tracks had people assigned to walk their length daily or even more frequently simply to check wether anything was amiss) Or they'd just approach it with the "Eh, some risk remains, watcha gonna do?" attitude...,(reply>), shinybaldy Even unarmored railcars are surprisingly hardy. You need a lot of explosives to actually derail a train and you're gonna need even more to damage the car directly. The bottom is after all made out of steel and there's a large gab between the car itself and the rails. Not to mention this car is at the back of the train. In order to blow it you'd have to pack a lot of explosives without anyone noticing and then precisely time the bomb to go off at the right time. This would be difficult and require precise knowledge of how long the train is and how fast it is going, which is probably classified information.,(reply>), shinybaldy I know in WWII there were some specialty cars created by armor plating some flatcars to run over tracks for the purpose of detonating any bombs on the rails, so I wonder if this is similar
