A portrait of Dahuichang Limestone Railway No.4. at work taking the empty wagons back to the quarry. These locomotives were based around a Russian design and built in China at the Harbin Forest Machinery Plant between 1977 and 1985. This locomotive was probably built in 1983 and is now at the Ffestiniog Railway where it is being restored and regauged.

Lots of information about the restoration project here: c2project.org/index.php?page=home
