PRR/CL&N - Pennsylvania Railroad/Cincinnati, Lebanon & Northern - Indiana & Ohio, Blue Ash and Mason Subdivisions
Historic photo of the PRR/CL&N tracks north of the Oak Street Tunnel, looking northeast towards industries at Stanton and Lincoln Avenues in the distance. Note that a gauntlet track was installed through these tunnels after a collision between two passing trains that couldn't fit in the tunnel at the same time.
