EMD GP-7

 

Colorado and Wyoming GP-7's #102, 103, 104 - among 4 diesel-electric locomotives purchased new by C&W in 1951 from Electromotive Division of General Motors.  We bought the three units from C&W in 2003.  The excellent C&W shops in Pueblo meticulously maintained the locomotives and they are in excellent operating condition.  We use these locos for train rides and to reposition equipment.  When taken out of road service and transferred to the steel mill, the "high hood" (long continuous front and reat hood) was cut down in front for better visibility in yard service.  The 103 and 104 have been repainted in the original C&W scheme using long-endurance polyurethane based paints. 

Our GP-7's utilize an EMD Model 567B 16 cylinder engine developing 1,500 horsepower.  This drives a generator outputting about 600 volts DC which is transfered to transaction motors on the two 4 wheel powered trucks.  Our units are designed for heavy hauling service and have a gear ratio of 65/12 which limits the maximum speed to 55 MPH.  Maximum continuous tractive effort is 52,400 lbs.  Fuel capacity is 800 gallons, lubricating oil 200 gallons and cooling water is 220 gallons.  Each unit is 55' - 11" long overall and weighs approximately 240,000 lbs.  

2,724 GP-7's were manufactured in all, only 16 are believed to still exist, almost all in museums or displays.  It is unknown how many units are still operable such as our three.  

We have repainted the 102 in the red, white and blue "bicentennial" scheme of 1975-76 used on #101.  The 101 was renumbered #200 in celebration of the 200th anniversary of our nation and was later sold to a short-line in Kansas.  It is now believed to have been scrapped.  We have duplicated this beautiful paint scheme with unit 102.
