Harry:
 
Aren't those the tenders that went behind the Y-4s?

Not  true. The only engine that had problems with counter balancing was the 
K3  4-8-2's, which had their main siderod connected to driver #3 instead of 
#2 for  more starting TE. They pounded the rails as driver #3 hopped above 
38mph and  it was those engines that were restricted to 35mph.

Not an N&W locomotive, but ACL's  Baldwin-built Class R-1 4-8-4's had  a 
counter balancing problem
also.  They were cranked to  the 2nd driver.  After a series of broken 
rails, cameras were mounted  on
the R-1s to record the rotation of the drivers.  It revealed  that at high 
speed (ACL was rigged for 90 MPH
running) one set  of drivers would lift off the rail.  They lasted about a 
year in  passenger service to
be replaced by EMD E-3s.  Following  a derailment at Stockton, GA (47 
killed, 41 injured),  ICC
Investigation 2813 attributed the cause to a broken rail  and noted "From 
January 1, 1940 to June 30, 1944,
this railroad has  reported to the Commission 61 accidents caused either 
directly or indirectly  by
broken rails. "  Of course, ACL was using  100# rail at the time.  Most of 
it had been rolled by  Tennessee
Coal, Iron & RR Co. in the 1920s. Believe the R-1  eight-axle tenders came 
to Roanoke to be converted into  canteens.
