I don’t get it at all. What else can they even use these for? No way they have enough battery range to run to GCT or on the branch lines

So no technical issue, just a bad decision to not extend 3rd rail?

Is that an M8 specific issue? Why doesn’t it affect LIRR?
February 25, 2025 at 9:17 PM
I see. Do you know if there were disagreements with Amtrak about extending 3rd rail up to the 60/25 Hz changeover?
February 25, 2025 at 3:17 PM
Yeah, more than twice as much current at the same mutual inductance. Bad oversight. Here’s hoping Amtrak ditches 25 Hz during my lifetime…

Shoes on SLE M8s are back, I saw one leave NHV with them a couple weeks ago.

Could you elaborate? Do you mean they can’t handle the current for 12 kV at 25 Hz vs 12.5/25 kV at 60 Hz? I’d imagine the rectifiers don’t care about 25 Hz vs 60 Hz, but 12 kV is likely a problem on its own

It’s a disaster. Took me two hours from GCT to T4 via Jamaica. People were stampeding for shuttle busses.

Just put in fare gates at GCT already

Sounds like there’s maybe a flat spot near the end of the train?
