Saw Youtube video of the first two metronorth charger units being sent out for testing at Pueblo. Video was from a few days prior to this posting.
Railroad Forums
Amtrak Empire, LIRR, MNRR/CTDOT Dual Mode Procurement - Charger Variants
- This forum will be for issues that don't belong specifically to one NYC area transit agency, but several. For instance, intra-MTA proposals or MTA-wide issues, which may involve both Metro-North Railroad (MNRR) and the Long Island Railroad (LIRR). Other intra-agency examples: through running such as the now discontinued MNRR-NJT Meadowlands special. Topics which only concern one operating agency should remain in their respective forums.

Note that the downward sloping part of the “warbonnet” isn’t nearly as curved as on the Genesis:

Guess there will never be a loco number confusion as Amtrak's 300 - & up will never meet with MNRR's location?

While I cannot find the image itself, the first dual-modes are currently under testing in Pueblo.

The first of Amtrak's APVs is not expected until 2026.
The dual modes in Pueblo are an MTA-led order for 33 Chargers (with options for up to 176) with third rail shoes and a forward escape hatch that replaces the MTA and CTDOT P32AC-DMs in the MNR pool. CTDOT, LIRR, MNR, and NYSDOT are all able to order options from this order. Delivery of the initial order of 33 units is expected to be complete in 2027.

Being able to assign the locomotives anywhere is actually a big issue. In addition, not needing to haul the third-rail gear around to places it's not being used also makes a difference.
by RandallW
There are locations in the NEC where third rail equipped locomotives wouldn't have clearance, so being able to assign any of the 83 ALC-42Es to any service without having to modify them is also important. I haven't seen one way or the other, but could having the battery to provide an extra boost in some locations, or to allow the train to run with diesels off in stations like Toronto and Montreal help?

Would there be enough boost to counter battery weight?
by RandallW
This is complete speculation and more informed people should correct this: the only things I can imagine are:
- Amtrak does not own any of the third rail electrification distribution systems that it uses and does not want to (or the LIRR does not want Amtrak to) continue to use third rail electrification in NYP and the East River Tunnels due to the age of the power distribution infrastructure and the needs to rebuild/renew it.
- That because the 3rd rail out of NYP is different than the third rail on the MNR, simply not having to ensure that shoe is properly positioned to work in NYP and not conflict with MNR third rail means removing a potential missed manual action to adjust while the train is at speed (and allows the battery units to be used on the NEC east of NYP without those crews thinking about the third rail at Pelham).
- The power draw for 6 (or 8) traction motors (I don't know if the APVs have one or two powered trucks) is simply pulling too much power for the third rail power distribution system in NYP to support.

Yes, our engineers have been engineered.
