There was a similar situation with the Williamsburg Bridge crash. The emergency brake operated at half their spec. The MTA's solution was to slow down all trains to match their inferior brakes."This too was not the whole story. There was the installation of larger traction motors which increased the train HP by 15%. Speeds were increased but the timing of the signals was never adjusted for the additional speed. Hence during an emergency brake application on the williamsburg bridge, the signals did not provide a large enough block for an emergency brake application. However, reducing speed should never be considered a permanent solution. The still need to find out why the new equipment does not perform as well as older equipment on these curves. The (video) report I saw sort of intimated that this was the solution. That's why I called bullshit. I had my suspicions all along that the issue was more related to the trucks hunting in curves but this is not based on any data I've gotten. |
