On June 18, 1961, John Gruber captured a sequence depicting the daily, all-stops local passener train of the Milwaukee Road going through a tunnel at Tunnel City, Wisconsin. The tunnel still is used daily. The image appeared on the cover of the November 1961 issue of "Trains," with the title: "HERE COMES NO. 58 ... in a remarkable movielike sequence of photos," a title bestowed by Editor David P. Morgan, who devoted four pages to the sequence of seven images. The train picked up and dropped off mail and express packages on its 12-hour, 20-minute, 421-mile run between Minneapolis and Chicago. Gruber used a fast-advance lever on his Pentax, rather than a motor drive. Few railroad or highway tunnels exist in Wisconsin, but were required occasionally in the unglaciated parts of the state, the "Driftless Area."
