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.

These were unusually powerful cars; they were fitted with 4 125HP traction motors so they could pull a standard 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 Domes 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 notable for a couple of things; first, they were meant to run under wire, so they have fairly heavy shatterproof glass & protective gridwork over the end windows, and secondly they have very tall domes, which were needed to fit onto a (7" shorter) RDC carbody and still give headroom on the lower level under the dome.

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.
