Long rusting in the park at Boise, this one belongs in the Hugo roundhouse, where it was serviced after trips from Denver. The caption says Fort Collins, Colorado, 9/10/56, but Ft. Collins normally only had one engine on the local. It looks more like LaSalle, Colorado to me, where the local engines were based.
