The arrows didn't appear on the drivers until about 1957 or so; the word at
the time was that a Roanoke Terminal engine was kinking rails somewhere on
the Norfolk Division. This was a long time after the K-3s were gone. The
word said that it was to provide reference points in connection with
high-speed movies. There were an awful lot of engines that didn't get
arrows - the Js, for instance. Bluefield assigned Ys. Portsmouth assigned
As.
I never heard if they found the culprit; the arrows were found on some As,
most Roanoke Terminal Ys, and Roanoke Terminal-assigned Ks. How an arrow
pointing at the edge of the counterbalance would assist in circumference
measurements is beyond what little mechanical comprehension I have.
