When the Parsons Vale Rapid Transit granted the PV&T trackage rights from Holderness to Tilton in 1916, they used some of the initial revenue from that grant (the PV&T needed to bring some sections of the ROW up to steam railroad standards, and the PVRT charged them a pretty penny for it) to update their fleet of passenger equipment with a handful of steel cars from St Louis Car. The PVRT’s first generation of passenger stock had been all wooden cars, which were all out of service by 1930 (they weren’t considered safe to operate on the line shared with the PV&T, which restricted them to operating on the Concord ↔ Northfield and Winnisquam ↔ Laconia sections of the line,) but the new steel cars survived the second world war and only started going out of service as passenger counts started to plumment in the late 1940s.

#300 was the last one in service – it was kept for summer service between Concord & Laconia, where it operated until the day when the Winnisquam bridge failed (it was running a trip up to Laconia at the time, but was still south of Franklin when the bridge failed and dropped motor 1018 into the non-briny deep.)

After the bridge collapsed, it was switched to MOW service (becoming PV&T #M965 after the PVRT was leased in 1965) for a couple of years before it was retired in 1966. But instead of going to scrap, it was stored in the Franklin carbarn until that property was demolished, and then went to Portland to be restored as a museum/fantrip car.

It still operates today.
