These white oval signs with blue edging are commonly found identifying bridges on the Tyne and Wear Metro. This particular sign was photographed at Pallion station on the Sunderland-South Hylton section of the Yellow line. The 1 mile 59 chains (from South Hylton) indicates that although it is exclusively used by Metro services it is owned by Network Rail - the Metro system uses metric measurements.
