You’re Correct!
There are several trolleys in the PTM collection that at one point contained a food preparation or dining area, but not Johnstown Traction Company 350. Most of these were added after the cars were retired and later used as cabins or cottages.
#115
Pittsburgh, Harmony, Butler, & New Castle Railway 115 served the North Hills until 1931 and is the only surviving car from the route. A motorman purchased the car after the interurban line was abandoned and relocated the car to State Route 88 (now 65) between Ellwood City and New Castle where it became a roadside diner. The restaurant grew around the car over the next 55 years, and it was extracted and became part of the Museum collection in 1986.
#739
West Penn Railways 739 served the vast West Penn network between 1925 and 1952 before spending 36 years as a home near Jeannette. As one of the longest cars to operate in the state, the car was upgraded to a parlor car for a brief period in the late 1920s.
Toledo
The Toronto Railway & Light Company built the observation car Toledo in 1906. The lavish car contains a kitchen, lavatory, and lounges with ornate finishes. The Toledo carried dignitaries to the World Series in Detroit in 1908 and was retired in the 1920s and used as a cabin for several decades. The Toledo came to PTM by way of Trolleyville and the Lake Shore Electric Railway Museum in 2009.
#274
Monongahela/West Penn 274 served both West Virginia and Pennsylvania between 1918 and 1940. The car is part of PTM’s “lived-in” fleet and served as a summer cottage in Southeast Ohio until the 1970s.
BONUS: Monongahela Railway Caboose #73
Cabooses were used by the railways as rolling offices and accommodations for the train’s crew. The 1949 Monongahela Railway caboose #73 at PTM contains a coal stove used for cooking meals and staying warm as crews often had to spend the night away from home.
