Red line runs on ATO?

Postby ctaman34 » Tue Oct 19, 2004 4:02 pm

Could someone explain to me since when does the Red Line run on ATO? I thought it was controlled by the operator.

ATO means "automatic train operation", in which even though the motorperson actually moves the train, its speed and other things are controlled by the Central Command Center in downtown.

However, I feel that such ATO on the Red line should be eliminated, because of the many screw ups it has caused on the Red Line, and just switch to general yellow/red signal, and the motorperson can even go any speed they desire, as slow as 6MPH to as fast as 75 mph. The latter could work especially on the South Shore/Quincy-Braintree Extension (Braintree Red Line), and even some long tunnel stretches too, we could use 63 MPH speed as well, all without the hassle of the Automatic Train Operation.

All of the trains are still ran by an operator it's just different when running a 01800 from the rest of the fleet. In the 01800's all you have to do is stop the train in the station. When running they automatically stay 1 mph under the speed even if the speed changes they automatically brake without the motorman taking any operation. I think the only times the motorman has to take any action is stopping in the station and taking off.

are the 01500's 01600's 01700's controlled by ato or by manual t/o operation

ATO, and the relay box is what blocks the window on the left side of the car!

I thought it was cab signaling and NOT ATO that the Red Line had? ATO signifies that the train is automatically controled by the computer, cab signalling means that the signals set the conditions for the train but the train is still run by the motorperson. Unless the T has become like the WMATA, the T doesn't have ATO.

01500-01800's all run with ATO which controls the speed of the train by the OCC. The motorperson are resposniable for starting and stopping the train and to operate the train if the ATO fails with manual blocking.
Farewell old friend thanks for the memories.

Yeah, that's right, but as I said in my previous post here, that ATO you are talking about should be eliminated and abolished to allow for greater speed flexibility.

Just run the Red Line like the Blue Line, in other words.

It's usually called Automatic Speed Control (ASC) in the industry. As implementated at the MBTA, "code" in the rails is read by the train's unit, limiting the maximum speed, no matter what position the controller handle is in. The train operator still brakes the train at stations and for reasons other than those automatically managed by the system.

As previously posted, true "ATO" is as implemented on systems such as BART and WMATA, whereby the train is operated entirely by automation, except for closing the doors.

On some international systems, such as Singapore's Northeast line, ATO is taken a step further: the doors close automatically as well (and people are well-behaved not to hold them). There is an employee on board, but (s)he roams the train. This is not very different from the way from many US-based airport people-movers.

Thank you for proving the information I lacked to back up my claim.
BTW you can add the London Docklands Light Rail line to the ATO systems as well.
