Cab Car Saftey Protection(is There Any)

I noticed in the ice 3m cab picture that theres nothing but a thin glass wall with door between the driver and the passengers there also a similar wall and door set up on almost ever cab car type train,so if a airplane cockpit has a secure door to try and keep intruders out,why don't these train cab cars have better barriers against intruders breaking in?You could cause a train wreck just as easy as a plane crash with such limited barrier protection.

 

I've often wondered the same thing.

 

If you incapacitate a pilot the plane falls out of the sky killing everyone on board and possibly some on the ground. If you incapacitate a train driver the train just stops due to the safety systems and all the other passengers batter the intruder for making them late.

 

Unless you turn sifa and pbz off.maybe then the safety system stops you.
