And this never happened during all the testing? Un-frigging real! You wouldn't think subway train doors are any kind of new technology, but I guess all the computer control is tricky new stuff. Shame. :(
During the testing they used plastic drums filled with water to replicate the Mk 1 human. That may work for overall weight, but wouldn't replicate a fully loaded train at rush hour with passengers leaning against the doors, walking/stepping on the threshold on, jiggling the doors (aka staring the closing process and reopening the doors before the cycle was complete). All of which adds up.

This sort of dead-weight testing evokes memories of the ill-fated Grumman Flxible 870 buses in New York.

Universal Hub reported Friday that the first two pilot Red Line cars from CRRC arrived in New Jersey by ship and will be trucked up to Boston.

It's a total joke and shame that the new orange line cars' doors broke within weeks of being accepted. I hope whoever designed them makes sure that the rest of the fleet gets that fix too! Other than that, they look really sharp. How are they going to test the red line cars if the test track is still under track work construction? Hasn't been an update on that and the red line improvement program in some time.

The new orange line cars have returned to service this morning though it's the second trainset. The first is gonna undergo more testing but will return to service soon. Also the first 6 pilot red line cars have arrived today at Cabot Yard in South Boston. They will undergo extensive testing being put into service. The MBTA predicts the first new red line train to enter service in the Spring of next year.

And yes, the bump stop component replacement with a heavy-duty is expected to be more reliable and yes that modification to the door component will be added on the rest of the new orange line cars

I have not had the pleasure of riding the new OL train yet, but I have several coworkers and acquaintances who have, and all complain about the door chimes. For example, one said the train was held at a station for a while, and the doors beep constantly while the doors are open, to the point of major annoyance. Are there any plans to adjust this?

Probably no, since the tones are for ADA compliance.

That is, the beeping is so that blind people can find the doors and know that they are open. At least I assume that's the idea. I have noticed that in Salt Lake City's newest cars.

Saturday, 11/16, I saw 1412 and 1413 on the test track running back-and-forth between Wellington and Sullivan.

How about keeping them in full time service? They had plenty of time to do their modifications for them and it's time for the older cars to go!
