The Santa Fe's F-units are now as much a part of history
as the steam locomotives they replaced. Indeed, the CF-7's many
of them became are now gone from the Santa Fe. Many CF-7's still
carry on as the prime motive power of shortlines from coast to coast
and border to border (and even in Mexico) as most were sold off
rather than scrapped or traded in.
For most of four decades the F-units symbolized the
Santa Fe. They vanquished steam, they served in every capacity from
power for premier passenger trains to mainline freights to branchline
and local freights and even to occasional use as switch engines.
They are fondly remembered by those of us who photographed them
in their later years. Ask any Santa Fe engineman who is still around
who ran them and he will tell you they were the best engines the
Santa Fe ever had.
Refer to Joe McMillan's book "Santa Fe's Diesel
Fleet" for specific information on renumberings of 16, 37,
and 300 class units, and his "Santa Fe Motive Power" for
specific information on units in the CF-7 program. Also pay particular
attention to John McCall's book "Early Diesel Daze" for
specific information on FT renumberings as well as build dates and
technical information on all classes of Santa Fe F-units.
I am indebted to Gordon Bassett, Stan Kisler, John
McCall, Joe McMillan, Jay Miller and John Moore for information
and photos. A very special thanks to John Signor and Bo Colson for
the use of John's painting for our cover illustration. Thanks for
your help, guys.
