If only it had been the Klan cars from their recent protest.

They had to assemble a teem from the shop with the needed tools to disconnect the remaining cables and hoses. Disconnect those cables and hoses. Couple a rescue train to the east end of the train and pull it to Falls Church Yard, Couple another rescue train to the west end and push it to Falls Church Yard.

Yep. The only thing that happened differently was that the lead 5 cars self-recovered to WFC Yard. Two rescue trains were used to pick up the passengers from both ends of the train due to the gap at the pull-apart.

Funny thing is that Metro said that they are going to inspect all 5000 and 6000 series trains.
What does the 5000 series have to do with this? Metro has retired most 5000 series trains from service.
I don't know how many are still in service and I have not seen a 5000 series train in quite a while

Good point. Upwards of 75% of the time I am on a 7k these days (Yellow or Green lines). The remaining percentage is divided between 2/3k series or 6k. Haven't seen or ridden a 5k all summer.

Both series have a similar two piece drawbar between the cars of the married pair.

It has happened on BART as well.

Actually no. This was a failure of a drawbar between a married pair. Bart does not operated trains composed of married pairs.

Like bart, WMATA has had several break aparts involving failures in their automatic couplers, this wasn't one of them.

I saw on a BART train, they have a way to walk between the cars. Unfortunately, Metro did not design their railcars this way.
Also, I read that the railcars are not designed to be married pairs

Metro - cause for 5000/6000 train separation

Post by JDC » Sun Jul 14, 2019 1:06 pm

We now know the cause for why a married pair of cars separated on the Silver line back in Aug. 2018. (https://wtop.com/tracking-metro-24-7/20 ... -railcars/) According to the WTOP story, it was "because the agency was using the wrong parts, installing parts that were used incorrectly, and not checking to ensure things were done right." https://wtop.com/tracking-metro-24-7/20 ... on-tracks/. The story has some great photos showing the incorrect type of bolts used to hold the married pair together, which failed and they separated as the train approach McLean station.

Of course, the 5000 series are no longer in service as Metro retired then in late 2018.
They should not have been mixing different series together, which they no longer do.
