...two USRA 2-6-6-2s, and one Mantua logging 2-6-6-2.  They all have that characteristic in and out of syncopation business programmed.  An articulated would sound strange any other way...


Hmm...  I thought only simple articulateds (e.g., a Challenger, Big Boy, or N&W A-class) went in and out of syncopation.   I would think a true mallet (which I believe the USRA 2-6-6-2 should be) would have its engines synchronized in a regular fashion...  after all, the low pressure (front) engines are fed directly from the high pressure engines' exhaust.  How could the phase relationship of the engines ever change?

Or am I confused?
