The issue has to do with continuity at wiring connections that could result in premature failure causing a great deal of time to be spent troubleshooting to find the broken connection.

It should be noted that this more of a performance and reliability problem then a safety problem.


These kinds of problems can be a bear to diagnose. Although I suspect it might get a little easier if they are aware that there might be wiring harness issues.

Are they going to install the chains at the same time they have the cars in to fix the wiring?

Knowing WMATA, probably not. :(

FTA gives thumbs-up to Metro’s expedited timeline for protecting blind passengers

Two months ago, Kawasaki said it found a way to retrofit trains by May. The FTA says that timeline is acceptable, as long as no more new trains go into service without the extra barriers.

"Although WMATA’s May 2019 commitment is later than the deadline stated in FTA’s June 2018 letter, given the additions to WMATA’s ongoing mitigation efforts, the nature of the supply and manufacturing constraints, and WMATA’s commitment that no new 7000-series cars will enter revenue service without the new chain [between-car barriers] installed, FTA accepts this updated work plan," wrote Henrika Buchanan, an acting associate administrator at the FTA.

Metro is now programming in announcements for which side the doors open.

WaPo has a story that Kawasaki is considering exiting the business of manufacturing railcars after a poor earnings report. https://www.washingtonpost.com/transportation/2018/11/02/company-that-makes-metros-newest-rail-cars-is-contemplating-an-exit-business/?utm_term=.84ad60e4ed79

Minor pedantic clarification, but these are not "programmed" in the sense that they're hard coded, the trains are actually reading the platform ID code from the TWC as they enter the platform limits and generating the announcement based on that input. This helps to ensure the correct message is played at terminal stations where either track may be used, or even when trains are single tracking for example. Cool stuff.

Typical lazy Wapo article, they completely left out the fact that Kawasaki made a strategic decision to exit the European market in 2014 to focus on the US. Seems they weren't able to compete here either, but the question is why. In Europe it's obvious: domestic industry titans like Siemens and Alstom have a major advantage.

Rode on car 7555. It has the chain barrier between cars, but not the original setup used to replace the rubber barrier. It's noticable different setup where bracket attaches to the car body.

I'm very surprised that Kawasaki fell down in quality when building the 7000 series cars. I only hope the same is not true of LIRR's new M-9 cars. Kawasaki first sold railcars in the U.S. in the early 1980's with an order of subway cars for Philadelphia and quickly got a reputation as a quality builder. If they were to exit the railcar market, it would be an almost earth shattering event, kind of like when the Mack Truck Corp. stopped building fire engines in 1984. :(

Just saw car 7565. I think. Went by fast. Besides the bracket being different, the metal barriers also appear taut with less sag.

I am surprised Kawasaki would consider exiting the railcar business. They made railcars for several subways in North America. They also made railcars for MARC. VRE had some too but sold them back to MARC. They were good quality, reliable railcars.

I'm not, the Nikkei is in a bear market and the Japanese economy is not doing well. The WMATA repairs is what broke the camel's back
