Rebuilds
There were 40 GP9M units built that are included in the 3,441 units built for United States railroads. A GP9M was built with parts from another older EMD locomotive, either an F unit or a damaged GP7. The use of parts from these older locomotives caused the GP9Ms to have a lower power rating than a GP9. This would be either 1,350 horsepower (1.01 MW) if the donor locomotive was an FT/F2 or 1,500 horsepower (1.12 MW) from F3/F7/GP7 locomotives.
Many rebuilt GP9s remain in service today with shortline railroads and industrial operators. Some remain in rebuilt form on some major Class I railroads, as switcher locomotives. Canadian Pacific Railway and Canadian National Railway still have many in their fleets in 2012 as switcher locomotives.
Several GP9s were rebuilt with a 1,500 horsepower (1.12 MW) CAT 3512 and re-classified as GP15C.

Famous quotes containing the word rebuilds:
“Really, there is no infidelity, nowadays, so great as that which prays, and keeps the Sabbath, and rebuilds the churches. The sealer of the South Pacific preaches a truer doctrine.”
—Henry David Thoreau (1817–1862)
