In the late 1950s, the PV&T made one last attempt to attract passengers to the rails by making a fairly large order of Budd RDC-bodied motors to operate the remaining passenger services between Bangor, Portland, Boston, Albany, and Montréal.

As was standard for PV&T passenger motors, these units are shorter (~3 meters) than Budd’s regular offering, but to make up for it they are unusually powerful cars; they were fitted with 4 125HP traction motors so they could pull a heavyweight passenger car as a trailer, or, in a pinch, be used as a freight motor.

Alas, despite the modern shiny power of these things, passengers were not lured back, and in 1971 the two remaining routes (Boston & Portland to Montréal) were dropped when Amtrak took over passenger service in the United States; these cars were then used for Boston commuter service until the MBTA moved the ex-PV&T routes over to North Station & the Boston & Maine in the early 1990s.

Most of the 10P cars were coaches, but 6 of them were combination cars for long-distance trains. Most of these cars went to scrap after their commuter years, but two (E76,E77) of them survived and are stored at the Portland shops.

Along with the 10P motors, the PV&T also ordered a couple of dozen control trailers; 18 coaches, 2 baggage, and 4 Vista Dome cars for the Boston/Portland to Montréal trains. Most of these cars were sold to museums and tourist railways in the late 1970s/early 1980s, but Vista Dome X121 was kept for the Parsons Vale’s business train.

The Vista Domes are pretty much run of the mill except that they have shatterproof glass & a protective barrier on the end dome windows.

These cars typically ran at the head of a train so that any wire entangling would happen well past the dome. This made them insanely popular for sightseeing (but not, alas, popular enough to make continuing to operate passenger service worthwhile.)

The remaining fleet was then stored at the TdM shops in St-Jean-Sur-Richelieu until the LT&L purchased the Chemin de fer Charlevoix, electrified it, and put several cars back into service hauling tourist & ski trains from Québec to La Malbaie, where they operate – after rebuilding with picture windows – today.

In 2022, the Toronto Suburban Railway started running a demonstration tramway from Brompton to Dixie using a pair of 10PCs that the Portland shops pulled out of storage, refurbished, and rewired to 1500VDC. As of 2025, they still operate on that demonstration line.
