Caption: One of 14 zebra GP9RMs left on CN's roster (5 in the Toronto pool) leads a rare trio of GP9RMs westbound as they highball down the Dundas sub after running around their train at Paris Junction. This particular trio was CN 4131, CN 7025, and CN 4136; who collectively had 198 years of service at the time the photo was taken. To my knowledge, there has not been another GP9 trio in London in the year since, although some wacky sets including 3 GP9s have occurred a bit to the north in the Kitchener terminal.
