We thought that we’d seen it all on metrorail. But sure enough, DCist saw the up-ended Red Line train that crashed into another one yesterday at the Woodley Park-Zoo/Adams Morgan. WMATA did its best to shield the view of the damage from riders with a blue tarp, but there is something very odd about seeing a metrorail car sticking up at a 30 degree angle resting awkwardly atop another train car.

The Red Line is single-tracked through all of the Upper Connecticut Avenue stations, but the delays only added about 10 minutes to DCist’s trip this morning, but we’re sure that others had different experiences (please tell us in comments).

We suggest you read the Post’s indepth look at what happened yesterday. Apparently the brakes failed on the empty train and emergency braking systems did not kick in as the train rolled backwards down the steepest grade tunnel in any subway system (who knew that it was right here, between Cleveland Park and Woodley Park …) and slammed into a train that was about to head into the tunnel.

Richard White, WMATA’s chief, says the subway is safe. (We also suggest you read the Post’s account on White’s damage control efforts …)

Anyhow, expect delays. Removing $1.5 million worth of splintered rail cars from underground rail tunnels is not an easy task.
