3. RE: Balancing, Counterbalancing and Dynamics (NW Mailing List)

That wasn't quite the end of it, Jeff.  They quit using the R-1s in high-speed passenger service and used them in fast freight service after that, trusting the passenger trains to new EMD diesels . . .

  Yes Gary and Ed, it was the ACL's R-1 4-8-4's that had some fairly serious issues with the counterbalances of their drivers.  These locomotives were equipped with speedometers, which was fairly unique for steam locomotives at the time.  Engineers were reporting to their supervisors that the needles on the speedometers were at times fluctuating wildly for some strange reason.  To find out what the problem was the motive power people placed movie cameras under the R-1's to see if the problem could be located.  When the films were developed, and viewed they showed that the drivers were actually lifting off of the rails at certain speeds.  The drivers were then re-counterbalanced to correct this problem, and as far as I know that was the end of it.

  Gary, did you mean the  ACL  R-1 4-8-4's built by Baldwin that had severe 
  counterbalancing problems?  I don't recall any of the RF&P classes of 4-8-4's 
  (never referred to as Northerns - they were Generals, Governors and Statesmen 
  from Virginia) having such problems.   ??
