Caption: I wasn't foaming this day, but for whatever reason had the scanner on and heard that train 335 (Garneau, PQ. to Buffalo, NY) had stalled on the 'Scarborough Hill'. It took a little while to get down to the tracks, but when I did was greeted with a unusual sight in the diesel era; headend helpers. Though helpers were most common here in the steam era from Don Yards as far as Port Union, a combination of better low speed pulling power of the diesel and the re-routing of most freights away from downtown via the York and Halton Subs had made this non-existant. Usually a heavy train with a good amout of steel out of Hawkesbury, it would seem that this 335 was too much for CN 6027 and CR 6666 to get over the hump, so 546's power, CN 4115 and 4101, came to the rescue. And yes, it sounded great! 1329hrs.
