Description
The former Selside signal box, built in 1907 for the Midland Railway, is a railway signal box that was relocated to Carnforth in 1976. It is constructed of timber and features a Welsh slate roof.
The signal box is square in plan and has two storeys topped with a shallow-pitched, pyramidal roof that includes a finial. The first floor operating room is surrounded by continuous glazing on three sides, except for the east rear, with windows divided into a row of four lights on each side. Each light is subdivided into six panes with glazing bars. The part-glazed doorway is located at the north end, which was previously accessed by an external flight of timber steps, though only the top landing remains. The signal box also has an external walkway with a handrail designed for window cleaning. The ground floor features a single window on the front (west) side and a door on the north side. The areas of plain walling are finished with horizontal weather-boarding, while vertical boarding is present above and below the windows.
Inside, the signal box has not been modernised and retains its original lever frame and associated equipment.
