I miscalculated the speed on the four videos I posted above (05-06-2019). The scale speed was 7.2 miles-per-hour and has been corrected in that post. I also tested my MTH New Haven GE 44-ton engine again today and ran it conventionally at 10 Volts, 0.3 Amps, at a scale speed of 5.4 miles-per-hour as shown on the two videos below. (The engine ran around a loop of track with scale distance 1158.6 feet in two-minutes and 26 seconds. That is a scale speed of 7.9 feet-per-second, 5.4 miles-per-hour.) Again, no problem through the Atlas O-54 curved switch path. I recognize that this track geometry is not as critical as a larger-radius turnout and it also has a flat-top rail profile. In addition, the wheels and track are very clean, the track connections are tight, and the track is level.
