The P&W originally used diesels under the wire for their traffic that originated or was delivered to industries along the NE Corridor, but the new management preferred to only run motors under the wire. So after the original order of electro-diesels had spent a few years running a batch of locomotives for the P&W were ordered soon after the D&H’s AC/DC order.

ILW’s eco-654fe model has a pair of slightly more powerful diesels (Cummins QSK60s) powering it instead of the Cat 3512s that the DP1s used. AC/DC units, too, so they could be used for runthroughs from the NE Corridor, onto the CV, and up into Canada under PV&T wires.

They served well in this service for 14 years, but were then pushed off the P&W when it finished its electrification. Now assigned to the B&Q, they are running on the LT&L/B&Q international line between Montréal and St John, NB.
