Will there be a new timetable to reflect any of the speed increases? Sounds as if they might be south of NY, as well as the classic 150+ sections of Acela in New England?

Amtrak is in the process of issuing IPads to T&E crews now so it should be a seamless transition depending on whether the paperless program is up and running fully.Ooo fancy, surprised Amtrak's IT department can handle that

Still quicker than copying down and reading back.)I would think dispatch would set the signal to red at the next block, send the Form D to the cab (or tablet), and wait for the engineer to call up and confirm receipt and read the Form D back... or relay the form D back down to the engineer.

By rule the dispatchers cannot signal a train up to or past a location where the train will be required to comply with a directive unless the directive has been issued to the train.ExCon90 wrote: ↑Thu Jul 15, 2021 8:37 pm SEPTA's Silverliner Vs are equipped to receive Form Ds in the cab, but I don't think they're operational yet.

Same with Amtrak. Set the signals to stop and call up, send the G.O. down to the iPad and cab, wait for the engineer to read it back to dispatch or complain.

This cut down greatly on missed repeats. Glad to see it's finally come to the corridor.

A change in signal indication by the dispatcher would only be immediately reflected in the cab if the train was close to the interlocking or CP, the Dspr has no direct control over cab signals and the form of PTC used on the corridor (ACSES) does not communicate with the cab signals unless approaching a signal displaying stop at an interlocking.That's my thinking as well. The dispatcher would signal at the start of block where it's affected... which would usually be at an interlocking.
