Today most of CP's hi-rail equipement is either wearing the white beaver sheme of the yellow CP Rail paint. Here we have a cross-over of the two, a classic yellow "CP Rail paint" Chevy SUV with the beaver decals and safety stripes added for a modern look. I love it, looks just like this "old school machine":

I'm guessing this is a supervisor's truck, since most hi-rails have a different numbering sheme. Following this logic there must also be BC. 101, AB. 101, MB. 101, ON. 101 and QC. 101, all with those odd looking wheel caps and a spare tire up front. The oversized Safety lamp and luggage rack add to its odd look.
PS. Note the Structures Supervisor parking in the next stall.
