Hello all
Running the longest steam engine on the shortest day .
PRR #6100 made its first test run eighty-five years ago today. The class S1 6-4-4-6 duplex had to run in reverse all the way to Huntingdon , PA (35 miles), because Altoona had no turntable large enough to turn her. She then ran forward to Altoona, attaining speeds up to 50 MPH.

The S1 designed for straights in a curved world . 8' longer than Big Boy ...made turning the speedy S1 near impossible .
Fixed frame duplex engine relegated the S1 on the Chicago to Crestline, Ohio run of the PRR ...when it was not racing north of 100mph it was on the ground in Crestline failing to negotiate the wye.
This O scale model of the S1 was built from plans submitted to Ed Alexander whilst the 12" to the foot model was being built . Both model and real engine were on display at the 1939 NYC World Fair lettered " American Railroads" . Alexander would make 2 additional S1's for the PRR one being displayed at the 1939 Treasure Island fair in San Francisco.
Model like prototype likes straights and will have nothing to do with my 48" radius ....running with outside third rail sweeps.
Please see link for video of S1 in action
