Winston Tunnel - History

History

The newly constructed Minnesota and Northwestern Railroad across northern Illinois utilized trackage rights on the Illinois Central Railroad between Dubuque, Iowa and Stockton, Illinois in 1886 before construction on its own line through the isolated wilderness could commence. Engineers quickly realized that a tunnel would need to be constructed in order to traverse the rugged landscape. The Sheppard, Winston and Company (for which the tunnel would be named) and more than 350 laborers worked by hand, digging through the silty and unstable shale for nine months starting in the spring of 1887. The work was backbreaking and dangerous, and at least one worker, a thirty-two year old Finnish immigrant named John Hill, was killed. When complete, the total cost of the tunnel, $600,000, had exceeded expectations.

The tunnel proved to be a constant nuisance to the Chicago Great Western and its predecessors. Almost immediately, railroad engineers realized that the unstable nature of shale through which the tunnel was bored, ground water seepage, and the isolated location of the tunnel meant repairs would be frequent and costly. The tunnel was originally braced by wooden beams when it opened to rail traffic in January 1888, but these eventually proved inadequate, to be replaced in 1902 by brick and reinforced concrete. Constant deterioration of the supports meant large-scale reconstruction of the tunnel would be needed again in 1912, 1918, 1944 and 1947.

The bore was also improperly ventilated at first. A shaft sunk into the top of the tunnel failed to provide enough fresh air, and the crews of the steam engines would often complain of the intense heat and smoke due to the poor air circulation. Piecemeal solutions failed to work, and by 1912 the railroad was forced to install a huge fan, powered by a 310 horsepower (230 kW) diesel motor and staffed by operators day and night, to ventilate the tunnel. The fanhouse, constructed by 1916, was abandoned by the CGW with the acquisition of diesel locomotives by 1947.

When the Chicago Great Western was federalized during World War I, a contingent of Illinois National Guardsmen were assigned to protect the tunnel.

The operating nightmares of the tunnel, not to mention the millions of dollars the CGW spent to keep it open, forced the railroad's management to consider many schemes to rid themselves of the burden. In 1909, 1951 and again in 1964 (the same year the North Western and Great Western announced their intentions to merge) the CGW sought engineering proposals to reroute their trackage around the bore, to daylight the tunnel, or to completely rebuild and improve it. To the often cash-strapped Great Western, however, all these plans proved far too expensive.

In the end, the 1968 merger with the Chicago and North Western (C&NW) sealed the Winston Tunnel's fate. The Great Western's main line through northern Illinois closely paralleled the North Western's own line, but through less densely populated and less commercially active areas. The steep grades of the line and the obvious financial burden of the Winston Tunnel also played a role in the decision to completely abandon the Great Western's trackage in the area. The C&NW operated its last train through the tunnel in 1971. Scrappers pulled up the tracks the following year. Upon abandonment, the C&NW placed chain-link fences over each bore of the tunnel to keep squatters and other trespassers out. A 1973 attempt to turn the right-of-way through Jo Daviess County, including the Winston Tunnel, into a rail trail, failed when ownership of the land reverted to nearby property owners.
