Hamering up Bozeman The canyon below Chestnut Mountain on Bozeman Pass is filled with the sounds of hard-working vintage EMDs pounding up the grade on July 2, 1994. A trio of SD9s, a SD7, three GP9s and a GP35 power an eastbound 640 local and fill the air with exhaust. Who’s who on the head end is as follows: No. 601 is the former DM&IR (note the nose bell) No. 127, followed by SD7 607 and SD9 606 (both former SP), SD9 608 (also former DM&IR), GP9 113 (former NP), GP35 402 (former DT&I), GP9 115 (former CGW) and finally GP9 106 (former NP). The location is at the old Northern Pacific station name of Chestnut west of West End, Montana. We followed and photographed this train all morning, and I only wish I had a recording of it here.
