Just a comment about the discussion:

I would think that a high-speed locomotive would want the minimum mass for a main rod.  The longer the main rod, the harder to keep the locomotive in balance at different speeds.  In other words, the main rod should be connected to driver set #2, rather than #3.

I can't think of any narrow gauge locomotives that normally operated at the speeds of the modern Northerns.  So, the balancing of the main rod wasn't quite as critical.  The manufacturer could couple it to driver set #3 without too many disadvantages regarding balancing and harmonics.

Just my 2-1/2 cents.
