Also documented are instances of Milwaukee F7 Hudsons straight-lining the graphs on their 120 MPH speed recorders for several miles on end. C. H. Bilty, the Milwaukee chief mechanical honcho at the time, estimated the actual top speed at 125 MPH.

N&W's Class J 4-8-4 610, with its 70" drivers, was documented as attaining a speed of 111 MPH by PRR supervisors who rode and ran it during its tests between Fort Wayne and Chicago. Although it is certain that other 4-8-4s ran faster than that, there is no other known DOCUMENTATION of a 4-8-4 running that fast. In other words, if anybody ever did, they never bragged about it . . .
