The '''P42DC''' (''GENESIS Series I'')<ref>P42 Builders Plate https://www.flickr.com/photos/76498245@N05/6871547365/in/photostream</ref> is the successor model to the P40DC. It has an engine output of {{convert|4250|hp|lk=in|sigfig=3}} at 1,047 rpm, or {{convert|3550|hp|sigfig=3}} when running in HEP mode (900 rpm) with a 0&nbsp;kW HEP load. As with the P40DC, traction horsepower in HEP mode decreases to {{convert|2525|hp|sigfig=3}} when providing the full 800 kW HEP load to the train.

The P42DC has a maximum speed of {{convert|110|mph|abbr=on|sigfig=3}} compared to the 103&nbsp;mph (166&nbsp;km/h) maximum speed of the P40DC. Tractive effort is rated at {{convert|280.25|kN|lbf|abbr=on|sigfig=3}} of starting effort and {{convert|169|kN|lbf|abbr=on|sigfig=3}} of continuous effort at {{cvt|38|mph}} given wheel power of {{convert|3850|hp|sigfig=3}}.<ref name="Page 14"/>

P42DCs are used primarily on most of [[Amtrak]]'s long-haul and [[higher-speed rail]] service outside the [[Northeast Corridor|Northeast]] and lower [[Empire Corridor|Empire]] Corridors. They will be replaced on long-distance service by 125 [[Siemens Charger|Siemens ALC-42 Charger]] locomotives between 2021 and 2024, but will remain in service on shorter corridor trains.<ref>{{cite press release |url=https://media.amtrak.com/2018/12/amtrak-to-improve-national-network-with-new-locomotives/ |title=Amtrak to Improve National Network with New Locomotives |date=December 21, 2018 |publisher=Amtrak |access-date=February 3, 2020 |archive-date=January 26, 2021 |archive-url=https://web.archive.org/web/20210126125526/https://media.amtrak.com/2018/12/amtrak-to-improve-national-network-with-new-locomotives/ |url-status=dead }}</ref>

[[Via Rail]] Canada has utilized P42DC locomotives since 2001, when they replaced the [[LRC (train)|LRC]] locomotives that year. They are currently on services with speeds up to {{convert|100|mph|abbr=on|sigfig=3}}, mainly on the [[Quebec City–Windsor Corridor|Quebec City-Windsor]] rail corridor.<ref>{{Cite web|url=https://corpo.viarail.ca/en/projects-infrastructure/train-fleet/locomotives-p42dc|title=Locomotives - P42DC &#124; VIA Rail|website=corpo.viarail.ca}}</ref>

====P42C====
The P42C is a [[Control car|Non-Powered Control Unit]] (cab car) converted by Amtrak from retired P42DC locomotives, with the first one converted in 2024. These retain their internal components for weight purposes. Amtrak plans to eventually convert 20 Genesis locomotives into P42Cs.<ref>{{cite web|url=https://www.trains.com/trn/railroads/locomotives/amtrak-npcu-cabbage-locomotives/|title=Amtrak NPCU 'Cabbage' locomotives|last=Guss|first=Chris|date=November 4, 2024|access-date=February 3, 2025|publisher=Trains magazine}}</ref>
