Volunteers helped to make sure Bo’ness and Kinneil railway was on track for its opening this spring.
Six volunteers from Scottish Water joined the regular Scottish Railway Preservation Society Monday Squad volunteers working on the railway.
They hopped on a works train to the wooded section of the railway line where the combined team tackled the task of replacing some of the timber sleepers.
SRPS Monday Squad co-ordinator James Robertson said: “The Scottish Water volunteers quickly learned what the job involved.
“They worked hard and were keen to tackle every aspect of the work.
“By the end of the day a total of 16 sleepers had been changed.
“Thanks to their help, that section of track is now fit for the steam trains to start running on April 5 which is the start of our season.”
The volunteering programme at Scottish Water was launched in 2011, allowing employees up to two days of leave to volunteer and help in the community.
Fiona Burley, Scottish Water’s volunteering programme co-ordinator, said: “I am delighted we have been able to help the railway with work on the track.
“Our programme allows employees to help charities and non-profit-making organisations in our communities with practical tasks they may not be able to manage on their own.
“Feedback from our employees shows they thoroughly enjoyed it.
“We hope there will be other opportunities to get involved with Bo’ness and Kinneil Railway in the future.”
It is hoped there will be more joint projects between Scottish Water and the SRPS which operates the Bo’ness and Kinneil Railway.
More than 60,000 visitors a year are welcomed to the steam railway and museum.
