ATO can exist without CBTC, and CBTC can exist without ATO (as in fact it has been on the L line for a while now). People also tend to be confused about Train Operators and Conductors. The Conductor is the guy in the middle of the train who opens and closes the door and watches to make sure nobody is stuck in said doors. The Train Operator is at the front of the train driving the train. The MTA wants to go to One Person Train Operation (which is already used on some lines), where there is only one person, at the front of the train, responsible for both driving the train and working the doors. The ATO system (which is built on top of CBTC) makes this job somewhat easier since the Train Operator no longer has to actually drive the train, instead he just supervises the computer.

Automated train operation is an element of communications-based train controls. In this case, the ATO functions won't be implemented. I’m not the only person who thinks otherwise.

A person will always work the doors. CBTC and ATO are 2 different things even though Ben seems to think otherwise.

Is there a mechanism already in place that will automatically reopen them, like a garage door? I'm running under the assumption that the regular (non-CBTC) train doors are manually controlled by the driver, but I'm not sure. Just curious what the CBTC will do if you get stuck in the door?
