Here is a nice video from the Illinois Railway Museum in Union Illinois. www.irm.org
I grew up in Chicago during the 1960's and 70's era, and I have happy memories
of the former Chicago, Burlington & Quincy Railroad, and the 1970 successor railroad
Although the Chicago, Burlington & Quincy -The Great Northern - Northern Pacific
and the Spokane, Portland & Seatle railroads had all merged and became the new
company Burlington Northern on March 2nd, 1970...many locomotives from all of the
companies rolled around the BN system until at least 1977, in their 1960's (And earlier)
factory paint schemes.
I fondly recall seeing many red and gray Chicago, Burlington & Quincy diesel locomotives
idling and working alongside green and black Burlington Northern diesel locomotives, at
the former C,B & Q Clyde Yard facility in Cicero Illinois in to the mid 1970's.
C,B & Q # 504, is an EMD SD 24 restored to it's original Burlington appearance
and operating today, at the Illinois Railway Museum in Union Illinois.
