A heritage railway association in Derbyshire is appealing for volunteers to help reopen a three-and-half mile line to passengers.
The Ecclesbourne Valley Railway wants people to help lay 150 sleepers on the Wirksworth to Idridgehay line.
The group wants to eventually extend the route to Duffield, making it one of the longest heritage lines in England.
Managing director Martin Miller said working on the railway would be a good way for people to get back in shape.
"The fact it's a railway is in many ways irrelevant, it's just a nice way of getting fit again and lose those Christmas pounds," he said.
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 aims to open the route to passengers in March.
