| Doodlebug. Here is an original photo that I took of Pennsylvania Railroad equipment in Hollidaysburg, Pennsylvania, on 18 September 1965. Shown here is the power plant of PRR #4666, a J.G. Brill Gas-Electric Model 660 "Doodlebug" built in June of 1930. It is a 12-cylinder, in-line engine rated at 415 HP. |
