CNO&TP Tunnel 20, originally bored in 1878. Was bypassed in the late 1940's during the double tracking of the railroad between CW Tower and Robbins. The tunnel is far out in the woods and requires hiking via some backwoods trails to get to it. Make sure you wear orange! It is also accessible by hiking up the mountain side from Highway 27 and crossing the current railroad tracks on foot, which requires caution. This tunnel does not sit directly next to the current railroad grade like sister T19. The former grade running south of the tunnel veers to the west quite a bit before lining back up with the current grade to make the run towards Rock Creek bridge and former Tunnel 21.
