I think it's crazy that the MTA hasn't already done this. Not only would it save a lot of lives, but it would also allow the platform to be climate controlled. You have no idea how many times I've sat there underground for 30+ minutes in sub-freezing or 100+ degree heat.

  And the advertising potential on BOTH sides of the wall!

  So we also have to pay for new HVAC systems on almost five hundred commercial buildings (that's what they are, even if underground) with no space for them? Cool.

  Crazy is too strong a word because the costs involved would be astronomical / extraordinary / insane.

  Platform doors are generally installed when you install modern signalling (CBTC) onto a line, which much of the NYC subway does not have. CBTC equipped trains can operate under Automatic Train Operation (ATO) meaning that trains can be made to always stop at the same location on the platform. Furthermore, platform doors require you to have trains that have the doors in the same positions on the car body, which much of the newer subway fleet (R142,R188 & R143,R160,R179) has but the legacy fleet does not. This issue get compounded even more where multiple lines intersect (which is often due to the NYC subway's unique connectedness) requiring that certain stations would need to support 3 or 4 different car classes.

They investigated installing them here (Toronto) but the cost per station is pretty high, on the order of >$1M per platform. When you multiply that across a system as large as NYC that's easily half a billion dollars. I'm not sure how many ads you have to sell to recoup the cost, but it's probably a lot.

  edit - thought we were still talking about a simple low wall or gate, not the floor to ceiling glass in the GP post. leaving below for posterity.. > on the order of >$1M per platform That's insanity! Over $1M for something every amusement park has for every ride? Lemme guess, these one have to be engineered to the point of 'impossible to fail' and installed by the employees of municipal cronies at 3x fair wages? Talk about perfect being the enemy of good...

    Insanity? That's dirt cheap. Think about how much mechanical complexity goes into each door, how it has multiple motors, servos, linear actuators and such. It has to be safe when closed, and it has to be safe when opened, it can't spontaneously shut in someone's face or pin them in the middle. It needs multiple sensors that can handle being exposed to a lot of wear and tear. It needs to operate for years on end with, ideally, very little maintenance. It has to endure being buffeted by the forces of the train entering and leaving the station which exerts significant strain on any hinges or track mechanisms. So you need a pair of these for each set of doors on the train, and if each car has three doors, and you have eight cars, that's 48 doors. That leaves you with only $20,800 per door. You still need to build the walls themselves and you need to have this installed by the right technicians. Do the math, don't bitch just because it sounds expensive.
