The Arrows are limited to 80mph currently, and were never allowed faster than 100mph. I've never gotten a straight answer as to why they're limited to 80mph.

For electric ops, NJT is the only ones besides Amtrak running any significant number of electric locos. Everyone else is EMU. Given the reliability of NJT's equipment, it's hard to say locomotives are any better from a maintenance / reliability standpoint. IIRC, SEPTA's loco hauled fleet doesn't do well either, despite getting LOTS of time between runs for maintenance, and a generally easy life. Also note the AEM-7s there barely outlasted the Silverliner IIs, despite the SL IIs being a LOT older and getting almost constant use.

I wonder if the cost of a train dropping dead on the mainline is partly why EMUs are becoming almost universal overseas for passenger ops?

They have been limited to 80 for about 20 years now. I recall ALP44s were rated at 125 on the NEC in the 1990s, are the ALP46s only 100 now?

Gladstone is usually Arrows. 10/12 car Arrows can found on the NEC, less so now.
