A passenger train is to run on part of a restored Derbyshire railway line for the first time since 1947.
The group eventually wants to run commuter trains on weekdays
Three-and-half miles (5.6km) of track between Wirksworth and Idridgehay has been restored by volunteers.
The first diesel train is due to depart from Wirksworth at 1200 GMT on Saturday as part of opening celebrations.
The Ecclesbourne Valley Railway wants to eventually extend the route to Duffield, making it one of the longest heritage lines in England.
Volunteer Richard Buckby said: "We're trying to transform what was eight miles of forest into a working railway which can carry passengers eventually all the way from Wirksworth to Duffield where we can connect with the mainline trains."
The group eventually wants to run commuter trains on weekdays and heritage ones at weekends.
