In August 1958, GM issued a brochure on the new air conditioning system available in transit models TDH-5105 and TDH-5106 and the suburban TDM-5108 after two full summers of testing in revenue service. The capacity was nearly twice that offered in GM's 41-passenger intercity coaches. This offset the effects of frequent opening of doors, large standee loads and prolonged engine idling. The air was chilled to 45 degrees which should provide a comfortable temperature 10 to 30 degrees below the outside temperature. The price was $4500. By comparison Chicago paid just over $20,000 per bus for its 8200 series Flxibles.

AC was expensive! My memory is that most of these units wound up on TDM-5108 coaches and transit air-conditioning did not catch on until the New Look era.

What may be under the GM oddity heading on the above bus are the double license plate wells in the back of the bus. I'm not sure if other examples exists.

Just thought I'd throw that in!

The rear window looks kind of like it came from a PD-4103....

frankie,

Not so odd when you consider that there were transit companies that required at least two license plates including the Omaha and Council Bluffs Street Railway Company that served Omaha Nebraska and Council Bluffs Iowa across the Missouri River.

They carried a plate for each state as seen on the front of O. & C. B. St. Ry Co. #758 (a beautiful TDH 4507).

Photo thanks to NorCal Bus Fans.

Regards,

Mr. 'L'
