Greater Dayton RTA (aka Miami Valley RTA)
The current GDRTA schedules can be found here, for both ETB and diesel. Be advised for daily service, Routes 3W, 4, 7 and 8 are mostly ETB; Rts 1, 2, 3E and 5 has only selected ETB runs. In the evening and on weekends, Rt 7 and Rt 8 are trolley.
UPDATE. As of November 2009, the only regular trolley service is on the daily 3W and 4, along with the morning and evening "franchise run" 1/2s. No weekend ETB service.
Big thanks to Dave Yoder for making the 1962, 1963, 1964, 1966, and 1967 schedules from his collection available.
