I found this mid 1970's era photograph of a Dayton Ohio electric trolleybus at My Link page

The city of Dayton Ohio, has long been a place where electric powered trolleybuses are still reigning strong after all these years. While Chicago and many other citties in the United States and Canada eventually phased out electric trolleybuses for various mechanical or economic concerns in regards to the maintenance and costs involved in daily operation, the electric trolleybuses have stood the test of time in Dayton.

Dayton Ohio, operated a large fleet of coaches from the Marmon Harrington Corporation during the 1950's and 60's and well in to the 1970's. The Dayton RTA and later Miami Valley Transit Authority, painted their buses for many years in this attractive yellow and cream colorscheme with blue trim.

Although the Marmons were eventually replaced by more modern Flyers and later Skodas from Europe, a small handful of the Dayton Marmon Harrington electric trolleybuses survive today.
