Abstract:
For many years a great deal of trouble has been caused to the engineers of the Chicago Great Western Railroad by the single track tunnel 2600 ft. long at Winston, Ill. This is driven through gray shale which disintegrates into fine clay on exposure to air. The overlying strata are full of water and the tunnel has always been very wet. When first built it was timber-lined, and in 1886 a portion collapsed, blocking traffic for many months. A brick lining was then placed inside the timber and the contractors were supposed to fill the space between the two. A 1 1/2 ft. grade is encountered throught the tunnel and the cast-bound freight traffic frequently requires double headers.
