As part of the agreement
between Bison Rail and North East Railroad, NERR CEO &
President Bob Artim agreed to
transfer certain locomotives over to Bison Rail to aid
them in their start-up. Two of these locomotives were
Hi-hood SD24's with a long and rich history. They
started out on the Chicago Burlington & Quincy before
being absorbed into the Burlington Northern. Their next
tour of duty was on the Maryland Midland, and from there
they went to Steamtown before coming back to familiar
territory as Fox River Valley units. When the FRV was
taken over by the Wisconsin Central, they went to work for
their 6th owner. This is where they were when they were
purchased by the NERR. While on the NERR they received the
usual excellent maintenance associated with NERR power, so
were in great shape to do their job on the BR. They were
originally purchased by the CB&Q on EMD order #5598 in May
of 1959, and carry serial numbers 25207 & 25212. Their
history can be traced as follows:

The SD24 was first introduced in May of 1959 and was
radically different from all previous SD models. It was
the first SD model to be recognized as a Big Six
(supercharged 2250+ hp C-C) as a result of being equipped
with a turbocharger (an EMD first). The SD24's were
equally at home hauling unit trains across the Western
prairies, or pulling hot shot freights up and down the
grades of Southern Railway's "Rat Hole Division" in
Kentucky & Tennessee. Externally, the SD24 was very
similar to it's predecessor's the SD7 and SD9, but had two
external spotting features. The first was the bulge on the
fireman's side behind the cab which housed the turbo
blower. The second was the torpedo tube air reservoirs on
the roof. This was necessitated by the optional 3,000
gallon fuel tank which every SD24 but one was built with.
There were a total of 179 SD24's built during the period
7/58 to 3/63. In addition, the Union Pacific ordered 45
cabless SD24B's. 48 of the SD24's were of the high hood
variety, going to the CB&Q and the Southern.
For those of you in the Midwest or traveling to that area,
you have a chance to see not one, but two preserved
SD24's. The first, painted in Fox River Valley colors and
sub lettered WC is at the National Railway Museum in Green
Bay, WI. The second is at the Illinois Railway Museum in
Union, IL and is currently undergoing restoration to
return it to it's original CB&Q configuration. You can
find specifications and drawings of the SD24 at http://www.irm.org/dieseldept/
and clicking on "Locomotive Tech. Data". Or you can click
on "Restoration Projects" to see a very detailed article
about the work being done on this locomotive.

The Maryland Midland
Railway (MMID) headquartered in Union Bridge, MD, operates
67 miles of track from Highfield to Emory Grove, MD (50
miles) and from Taneytown to Walkersville, MD. (17 miles).
The 50-mile segment is part of the old Western Maryland
mainline. They move over 6000 cars of freight a year. A
large portion of this freight consists of cement,
fertilizer and grain and as a result of this covered
hoppers make up most of their freight cars. You can learn
more about the MMID by going to their officieal website at
mmidrwy.com.
The Fox River Valley operated approximately 114 miles of
track from Granville to Green Bay, WI. It was purchased
from the C&NW by Itel Rail Corporation in 1988. On 27
August 1993 it was sold to the Wisconsin Central and it
and the Green Bay & Western were combined under the name
Fox Valley & Western, which was a paper road only.
