GM Truck & Coach Division

1911 – General Motors Truck Company

In 1909 GM acquired Rapid Motor Vehicle Company in Pontiac Michigan. In 1908 General Motors acquired Reliance Motor Car Company. In 1911, these were combined into “General Motors Truck Company” and operated from Pontiac MI.

1923 – John D. Hertz Started Yellow Coach

The Yellow Coach Manufacturing Company was a builder of passenger buses starting in 1923. Yellow Coach started as a subsidiary of John D. Hertz’s Yellow Cab Company. They filled the need for low-chassis conventional buses.

GM Model Names Explained

We used this UtahRails.net as well as the General Motors August 1968 Engineering Standards as references for model numbers such as PD-4501’s:

  • P = Parlor (Intercity)
  • D = Diesel (until 1968)
  • 45 = Number of Seats
  • 01 = Series 01

Some coaches, such as the PG-3701, were also specially made for Greyhound. In those cases, they had an extra G (e.g. PGG-3701) denoting them as Greyhound-specific configuration.

Parlor, Transit and Suburban Types

What do these terms mean?

  • Parlor Coaches are long-haul highway buses – are often equipped with comfortable seats and amenities such as air-conditioning or bathrooms.

  • Transit Buses are city buses – include rear exit doors, and seating optimized for standees.

  • Suburban Coaches are inner-city transport buses – often used as commuter coaches.

  • Overseas Coaches were coaches built for export.
