Bingo. Somebody at Amtrak Dispatching in Philadelphia triggered the wrong switch at Zoo Interlock. The line ends at Bala Cynwyd because they tore up the line past there, and the old bridge over the Schuylkill carries no rail because it's falling apart. Past the old bridge, the line to Manayunk and Norristown is a bike path. This is a major embarrassment for everyone concerned.

It could have been worse. The dispatcher could have sent that train into a head-on collision. Somebody's career is going to be snapped like a matchstick.

"The dispatcher could have sent that train into a head-on collision."

I don't think that is possible, or at least it's extremely unlikely by using the signal system. Even if the dispatcher tried to line the signals, there are fail safes in the field to ensure that can't happen.

That being said, train crews can pass red signals under instructions from a dispatcher.

Thanks, my comments assumed the line out of Bala Cynwyd continued— so that a head on might have been possible. Switching error, and also— the engineer not noticing.
