Olef Valley Railway

The Olef Valley Railway (German: Oleftalbahn or Flitsch) or OTB is a 17.8-kilometre-long, single tracked, unelectrified branch line from Kall through the Schleiden Valley above Schleiden to Hellenthal. The line is currently only used by tourists, travelling on the heritage railway in the summer months, and occasionally by goods trains. However, there are attempts to reactivate passenger services that were ceased in 1981.
