When VIA Rail Canada retired all of their FPA/FPB-4s, the JLP joined in the unseemly scramble for units and ended up with 3 A and 2 B units. They were quickly outfitted with reset safety devices (the reason that VIA dumped them; the Canadian Transport Commission mandated RSDs on the lead units of passenger trains after a VIA train collided with a CP freight, killing 23 people in the process. VIA didn’t want to spend the money updating these units, but the JLP did) and leased back to VIA for a few years before the tide of EMD F40PHs flushed all of the first generation units off the system, then kicked around various shortlines & tourist operations (4702 was wrecked during one of these leases, and then sat in the deadline until 2018, when it was rebuilt with a Cummins QSK50, and then leased to a tourist railway in the United States), but by 2020 all of them, modulo the 4702, were out of service and scheduled for rebuilding with new prime movers & an ac drivetrain.

In 2024, 4 more FPA-4s joined the JLP’s fleet; the Napa Valley Wine Train traded theirs to ILW (with the understanding that they would not be scrapped), which then remanufactured them as FP-450As (Cummins QSK50 prime movers, AC drivetrain, and the cabs updated with a safety cab inside the skin of the original FPA-4 cab.

The LT&L, facing a motive power shortage after the United Railways Trust merger, has purchased two of the JLP’s FP-450 fleet (4703 & 4704) for freight service in eastern Ontario.
