Burlington’s Alliance – Casper train 31 behind E8A 9966 pops out of cool, dark Tunnel 1 just east of Guernsey, Wyoming, and into the heat of a mid-summer afternoon. The tunnel is one of three along a nine-miles section of track constructed in 1915 to connect separate Burlington lines at Guernsey and Wendover. Two decades after this picture, one of those tunnels, Number 2, will be daylighted and sidings lengthened along the entire route to accommodate the flow of coal out of the Powder River Basin. By then, passenger service along this scenic line will long since have run its last, Train 31 tying up permanently on February 28, 1966.
