it seems for about a week now that the ngec.org is down.

If they only maintained the axle ground brushes better there would not be a problem. Each axle has a carbon brush grounding it to Car body, maintenance has been shoddy on them.

The Contract for 145 Multi Levels is canceled, The cars ordered in 2017 were way overdue and lots of problems. https://www.inquirer.com/transportation/septa-train-car-contract-canceled-20240412.html?fbclid=IwAR05tNHFczm9BIew7hUa3AaoySB7gkDiaPWyxuDP6gJFIYbpVazQ-QjKlhY and...

The equipment for Empire service will not be Amtrak, but NYDOT and they did not order Airo sets

Amtrak (state of NY ) has not ordered dual modes yet. but base order is 125 already from original 75.

roof exit is a FRA mandate but on dual modes there will be a modification to fireman's side window. egress is over console and a rope type ladder down to coupler level . note: that picture in my post is not actual Metro North unit but a photoshop. the trucks lack third rail gear and fireman's...

Reason third rail operations is expanded is that new Dual modes have a energy storage module that will keep HEP alive in gaps. so HVAC's do not get damaged. the P32acdm's did not have an option for that. The module does not power locomotive in gaps.

not sure, report is from New Generation Equipment Committee.

#301 just about ready for testing. https://ngec.org/wp-content/uploads/2024/03/305-activities-report-monthly-2-29-24.pdf photoshop picture only for reference :

from NEGR site : Amtrak Equipment Procurement Update as of 2-29-24: On the Acela: Staging and testing continues – they are about halfway through Stage 1 and are optimistic that it can be wrapped up in a month or two and move on to stage 2.On the Airo trainset: Progress is strong – there are 34...

now your getting confusing , transition has nothing to do with gears or shifting, its reconfiguring the electric circuit to traction motors. Series - parallel - and field shunting , the mechanical configuration does not change.

not sure were you got that drawing but here is picture of real RDC throttle

Having worked and ran both RDC and SPV as Electrician/ MofE foreman/Engineer . no source from outside.

120" is not interior wide, but car width I believe, distract about 5 inches on each side for insulation and wall panels.

MCB is Main Circuit Breaker

statements from MTA now is out of service train did NOT have a favorable signal. the Revenue train did have a green signal

find it odd that no one has mentioned that unless one train ran a stop signal, it could only mean a faulty track circuit. as has happened at Marble hill a long time ago on Metro North

streamlining is mainly aesthetics, the most drag is actually the space between cars where they are coupled.
