The 2000 series cars had software problems too (such as related to the rollback business mentioned in the NTSB report).In the Woodley Park incident, there was a ton of operator error. But the 2000/3000 series overhauld by Alstom were the only cars at that time, I think, that had rollback protection while the engineer was operating without ATC and only with ASC. The train that rolled back in that incident was a 1000 series, as I recall. The engineer of the train that rolled back seemed just to have fallen asleep with his eyes open, though, which is curious, since he was operating under ASC. Had he been operating one of the overhauled trains, the rollback protection would have been prevented collision. But also, had he applied the brakes, that too would have stopped the train. |
