Since the boiler weight is suspended between the two engines, would it 
not still have just about as much traction as a standard articulated?   
Also the tender shell weight is also still on the engines rather than 
being drug behind. Granted full tanks and bunkers would give the best 
results and, since they are usually full when starting a train, I can 
see where that would be an advantage.

Wonder if any American loco builders or individual roads did any 
research or comparisons between Garretts and our standard articulated 
locos ??

While not exactly pure N&W stuff, it is an interesting discussion.

  Take care
Bill
