Caption: CP WHB-25 (Worktrain Heron Bay sub) goes to task switching out their short train of tie gons in the East end of the yard before running around to the West end of their train, putting the SBU on the van and departing Westwards to tie down in Marathon, 63 miles to the West. This was the first chance I've had to lay eyes on these new SD30C-ECO's, I was surprised at how quiet they run! Very sharp looking units.
