PL42AC thread

[ApproachMedium]

Thats a time consuming thing. Theres no wayside on the station platforms and trains running layovers of just a few hours or less it does not make sense to do. Plus there is often not any personell around to connect it. It isnt just like a electric car where you can plug it in and go. You need to reconfigure the locotmotive, shut it down, blue flag the track and connect the ground power. Reverse for when its undone.

In particular, locos built in 2015+ are supposed to come with start/stop systems that do not allow idling for over 30 minutes. But you're right, apparently CARB is toothless in this regard, even in its own back yard. Too bad.

HEP needs to stay running so auto start stop doesnt help

Eight new ALP-45s to replace some PL42ACs!

https://trn.trains.com/news/news-wire/2 ... e-purchase

NJ Transit’s board of directors has approved the purchase of eight Bombardier ALP-45A dual-mode locomotives, adding to a purchase of 17 of the locomotives that was approved in 2017. The new order will cost approximately $70.5 million, with delivery expected to begin in the first quarter of 2022. In diesel mode, the ALP-45A will meet EPA Tier 4 environmental standards. They will allow retirement of some of NJ Transit’s Alstom PL42AC locomotives, which have EMD 710 prime movers that cannot be upgraded to meet the current environmental standards.

Only 20 years of service and the PL-42s get scrapped while the GP-40s get rebuilt again for service on the AC Line.

Wonder if NJT considered repowering them with Cummings prime movers??

Theres a few PL42s that are wrecked now anyhow. And now that the AEM7 ac is not being used, the PL is the only US loco i believe using that propulsion package from alstom in IGBT. The same controls are used on the HST and HHP.
