All Things WMATA 7000 Series

[JDC]

I was on a train today where the LCD screen was a static image of a larger WMATA map and a 'tips for riding Metro' list. That was a new one.

Are there any high res photos of the underbody equipment on the 7000 series trains?

Can someone, maybe dcmike, definitively answer the question if the 7000's draw more power than the legacy series cars? I thought I had read somewhere back on the forum that their power draw is roughly the same, but I can't find that at the moment. I suppose the most interesting datapoint is any difference in power consumption during acceleration. Thanks in advance.

question about the 7000 series train computer system, i've been told that the passenger information displays run on windows boxes - does the entire train computer system run on windows too?

[JackRussell]

I have seen people post pictures of WER (Windows Error Report) dialog popups, so yes the information displays do run Windows.

The thing I don't get is that the people who designed these things ought to have added better error handling capabilities, and a watchdog process that can kill/restart the actual display process in the event of a crash, hang or other failure.

As for the rest of the railcar, I have no idea. I would tend to doubt it.

Anybody notice that the 6Ks have pretty much disappeared off OR/SV? Are they all on GR/YL now?

[Chris Brown]

I believe so. I don't see them on the red line anymore either.

By the way.. has ANYONE seen car #7400 yet??

Today I took a ride on car 7381. With 20 cars arriving a month, I'm assuming WMATA has received car #7400 by now or will in the very near future.

I saw a train last week with car 7399...so it must be out there now, or very soon.

There was a time back in the 90's when you never saw a 1K series train on the Red line ever. Red line was strictly 2k, 3k and 4k.

I remember in the 80s (late '86-early'87, it was the other way around, Red Line was 65% 1K, 34% 3K, 1% 2K when I rode it and lived in the area. The 2Ks were confined mostly to the BL/OR at the time (there was so GR, SV and YL was just a stub truncated route from Gallery Pl to Huntington and that line then saw mostly 2Ks and very few 3Ks

In other notes, it looks like a small amount of 6Ks have returned to OR/SV. I saw 7396-7399 on GR last week but it's now on SV ... doing firmware updates out of WFC annex perhaps?

I love how the ATU Is responding to this as if WMATA did this intentionally to hurt their personnel, and that WMATA endangers their personnel all day. The ATU is responsible for nearly all of the safety, mx, and mechanical problems in metro. They don't even step up when their own people try to kill each other on purpose. What a joke.

Update: Metro's press release seems to indicate nothing was/is wrong with its inspection protocols, just how they were being followed by employees. https://www.wmata.com/about/news/Metro- ... resume.cfm

Well what a surprise. The ATU lied as usual.

We have crossed the 7400 mark. 7400-7401 in service on OR/SV
