CN GP9 family types

Originally, CN GP9s had high short and long hoods and most were set up to run long hood forward (controls on right hand side with long hood pointing forward). The CN GP9s in service today (model GP9RM) have been rebuilt from older GP9s. In the process of rebuilding, the high short hood has been reduced in height to give visibility from the cab over it. Most, although not all, are equipped with cylindrical horizontal spark arrestors on the exhausts; in the photos above, 4017 and 7239 have the spark arrestors while 7049 does not.

The GP9RMs in service today are in four groups:

4000-4036: These locomotives are used to pull trains generally on the lower traffic branch lines. They are restricted in the amount of fuel they carry and this reduces their weight. They are not certified for operation in the U.S. They are painted in the CN black and white zebra stripes with a black cab. The control stands were changed to facilitate short hood forward operations.
4100-4143: These look the same as the 4000 series but can carry more fuel. This makes them heavier. They are certified to operate in the U.S. Control stands were changed for short hood forward operations.
7000-7083: These are used as yard switchers. Most are painted in the CN noodle and black cab although some have the newest CN paint scheme (CN noodle and one stripe). They retain the long hood forward orientation of the controls. Some are equipped for remote control operation.
7200-7280: These are used as mothers for slugs for low speed switching operations. Most are equipped for remote control operation and inside control stands are set up for long hood forward operation. Some are certified to operate in the U.S.
