New Red and Orange Line Cars

[bigeman312]

Alas, G1 door on car #1913 is not working. First time I have seen a new CRRC car with non-operable door.

I assume that’s something that happens on any subway fleet from time to time and can usually be fixed in a day. Am I wrong in that assumption?

Weren't there door problems on the very first few cars with them opening (or not closing)?

What is involved in the testing of new cars before service entry? The T roster on transithistory.org was recently updated, but they still haven’t accepted any cars delivered since August. I would expect midway through serial production, they should be able to accept cars quicker.

They've been delivering 2 cars each type monthly. transithistory must've been behind.

Edit: nvm I misunderstood what you were saying my fault.

As far as I'm aware they need to test all train control and signaling processes as well as a certain amount of time/mileage on the actual rails through each switch, signal, interlocking etc. It looks like the cars through Sept. are accepted on the Orange and through July on the Red. I assume they're being extra meticulous with it due to being under FTA scrutiny but also testing on the full trackage would be impacted by the big shutdowns this fall/winter. Set #4 of the Red Line is supposed to go active this month so hopefully they can get back of track with the track work done.

So they need to test on the main line, not just the test track?

Yes. If there's a wonky cab signal unit on the train they need to find which mainline signal is causing a glitch/dropout, so test track won't do for final certification. Plus the burn-in miles are significant, so they need to let 'em rack up more mileage than just pinging back and forth on the test track will allow. They'll be out on the off-peak and overnight. TransitMatters' new train tracker picks up the pings from the test trains, too, though to tell it would depend on whether an unaccepted car is leading the train vs. a borrowed revenue car trainlining with some unaccepteds.

Thanks for the explanation. I never understood why it seems like an entire train has to be held out of service though? Like we have 3 full trainsets but only two in service at any given time. Is it just the third trainset is still in its burn-in period?

If the cars are accepted, they're rostered and usable for full revenue service (whether or not there's a divisible-by-6 number of them on-hand to make up a going-concern revenue consist). It's only the delivered-but-not-accepted cars not yet on the roster that are subject to burn-in testing. Cars that are having teething problems or are scheduled for warranty mods in the shop would obviously be held out of the day's revenue pool even if they are "active" and rostered for service, so the number of consists does tend to lag the "active" numbers by a bit.

Red's had 24 active CRRC cars on NETransit for over a month now, but the 4th active 6-car revenue consist divisible from those numbers has been elusive so far so some of the earlier-delivered cars might be temporarily idle for warranty mods.
