The Winston Tunnel is the longest tunnel ever built in Illinois at almost a half mile. The Sheppard, Winston and Company started construction in 1886 and was completed in 1888 where it was turned over to the Chicago Great Western Railroad. The tunnel maintenance was the chief reason that the CGW was close to bankruptcy and sold out to the Chicago and Northern in 1968 who closed the entire line in 1972.
