The land originally belonged to the Sensabaugh family, who sold it to the CC&O Railroad. The hill was blasted in the 1920s and became the tunnel we know today. The Sensabaugh tunnel of fame and legend isn’t actually the Sensabaugh tunnel. That is the Sensabaugh Ridge Tunnel some distance away, and it is for train traffic.
There is no record, whatsoever, of any disappearance, child murder, murder, or hobo robbery. The stories didn’t start until the 1950s and 1960s. Ed Sensabaugh was a perfectly normal family man, and did not go crazy or murder his family.
