A present day view of the abandoned 975 foot long Manunka Chunk tunnel, built in the 1850s. The tunnel was always prone to flooding, despite the railroad's attempt to divert a nearby creek by wooden flume. The Lackawanna Cut-Off opened in 1911, spelling the end to most freight and passenger service on the original mainline. Track was removed from the tunnel in 1942 but a small section remains today, trapped between two cave-ins of the westbound bore.
