Image 15. After spacing and turning over, the rerolled 
rails are cool enough to be moved on to the Finishing 
Mill to be cold-straightened, chipped and drilled.

Details scanned from the original print:

  b. Detail

Note: The mechanical details are not quite apparent
here, but there had to have been a way to move the
rails seen in the foreground closer to the viewer as
the additional completed rails accumulated in the 
background.  One can see some of that mechanism
in the immediate foreground.
