Completion of the Teton Valley Railroad - 1913

By 1913, the Union Pacific railroad had completed a line from Aston, Idaho to Victor, five years after offering the first "Yellowstone Special" on June 11. 1908. The rail dead-ended in Victor, and steam trains were turned around there on a wye (a triangle shaped junction that allowed a trail to back up and turn around.) Passengers heading to Jackson, Wyoming then took a carriage, or later, a bus, over the Teton pass, which by then was still a difficult, though not impossible, journey. The photo above shows the inaugural train - UP #684 - with a second engine and at least 6 passenger cars, probably somewhere between Driggs and Victor. The photo below, given the position of the boxcar with people standing on it in both photos, is probably taken on the top of a car on the track, either before or after the first train rolled through. The population shown in the photo below most likely represents the sum total of residents in the Driggs/Victor corridor.
