I’m very sorry. I really hope and pray that’s not the case.
As an aside, I would very much like to see calculations regarding what the forces are at different speeds for the old and new Metro North cars at all these types of locations where there are curves. Maybe they need to rethink their rules of operation for these trains.
Metro North is a disaster as is New Jersey transit. They simply don’t care about their customers. This morning a Metro North official bristled nastily to a reporter when he suggested that there may be more fatalities than 4. Now, of course, it looks like the reporter was right.
There are some significant curves around the Spuyten Duyvil station. Heading northbound from the station the line curves to the right while following the Harlem river, and then marks a sharp (by railroad terms) turn to the right where the line follows the Hudson River up to Albany. Speed through that set of curves would not vary dependent on what passenger equipment, unless it is bilevel (due to center of gravity), which I really doubt can get through the Park Avenue tunnels to Grand Central Terminal.
My guess is that the train went into the curve too fast.
