Derwent Walk Express
Andy Frost's Derwent Walk Express is probably the only locomotive which tows its own passing landscape behind it.
This colourful sculpture acts as a sign for the Swalwell entrance to Derwent Walk Country Park, an area restored and landscaped as an urban improvement scheme.
The painted plywood construction (2.5 x 33 metres) combines a steam train with slices of countryside - plants, birds, animals, insects and a distant power station. Mounted on the bridge abutment of a railway viaduct on the former Derwent Valley branch line, the sculpture reflects the area's great railway heritage and its present regeneration as a country park.
Installed in 1987 but has been recently refurbished in 2005.
