Caption: Codeline poles fly by as CN GP40 4017 speeds northbound on the Newmarket Sub leading 5 old 6-axle commuter coaches on the "Barrie Bullet" somewhere south of Barrie. The exact location of this photo isn't noted, but it appears to have been shot between two rural crossings relatively close together.

The two 89mph-geared CN GP40 units (4016 & 4017, later 9316 & 9317) did time on CN's and later VIA's passenger trains out of downtown Toronto's Spadina Roundhouse, and even worked in GO Transit commuter service. One of the assignments they often drew was the "Barrie Bullet" commuter trains between Toronto and Barrie. One of the 3000hp units solo was pretty much enough, and it lead long hood forward on the trip back.
