Field is a railway town on the Canadian Pacific Railway about halfway between Calgary and Revelstoke in the Rocky Mountains. As well as a crew changing point, it was once a helper station where extra locomotives were added for the push up the “Big Hill” which starts eastbound straight out of town. Higher powered locomotives and AC traction motors have now dispensed with helpers, the extensive yard now just a staging point for massive trains awaiting fresh crews. Crew changes for those trains not staging over and going straight onward, are often done down at the road crossing at the east end of town just out of the yard. Crews from Calgary alight here to await another train for a turn back home, and vice versa for those coming up from Revelstoke. Fresh crews from the bunk house and beanery are bussed the short distance to the crossing, the bus then collecting the incoming crew. As most lines are single over great distances passing points are the normal out here. Footplate crew are expected to get down to the lineside for a mark one eye ball inspection (known as a roll bye) of the train passing them in the opposite direction, for smoking hot boxes or stowaways hiding in the car ends. So the scene in the photo is set. 8933 east has arrived first, pulled up to the crossing and a crew change over effected. 8876 now slowly grinds to a halt having descended the hill, and has its crew changed out. 8933’s crew is out for the roll bye. Having a radio scanner for train watching in America and Canada is essential if you want to know what is moving and going on. Whilst stood at the crossing taking the shot and watching, this is something like the dialogue that we were listing to. 8876: “8876 west to dispatcher” Dispatcher: “Dispatcher answering” 8876: “Okay sir, we are all ready to go if that fits with you, what’s it looking like ahead?” Dispatcher: “Okay 8876, go on my signal. I have you clear to Golden, then a meet with an Eastbound, give me a call when you’re getting into town” 8876: “Thanks for that, leaving with a green light on the main.” Train passes slowly over the crossing, taking nearly 15 minutes to clear. 8933: “8933 crew to 8876 west - good roll bye, have a good trip” 8876: “Thanks for that brother, have a good trip yourself, catch you next time” 8933: “8933 east calling dispatcher” Dispatcher: “Dispatcher answering” 8933: “Good to go whenever it suits you sir, how’s the road ahead looking for me?” Dispatcher: “Go on my signal 8933, you have track work at Eldon so you’ll go through the siding, engineers holding the main, and I have a meet for you at Banff, the Campotex has already left Alyth (Calgary yard) and on its way. Get back to me we you’re approaching Banff.” 8933: “Thank you for that sir, 8933 leaving Field with a green on the main.” The next thing is the scanner cracks into life again, the hot box detector reports (in its mechanical voice) on the 8876 west by now near Leancoil: “CP detector milepost one four point two, four six zero axles, speed two four miles per hour, temperature one eight degrees, no defects, detector out” Time to return to the bar at the Truffle Pigs in Field for one more Canadian Malt Beer and pouring over the maps for the hike to the Continental Divide and the Summit Lakes shots tomorrow.
