Arnside Signal Box

Arnside Signal Box is a railway signal box built in 1897 for the Furness Railway, designed in the Furness Railway Type 4 style. The structure is made from Carboniferous Limestone with irregular squared stone at the front and rubble at the rear, complemented by Devonian Sandstone quoins and other dressings. It features a slate roof with terracotta ridge and finials.

The signal box is two stories tall and built into the side of a railway embankment, making the ground floor, which houses the locking room, appear as a half basement from the trackside. The ground floor has a high, battered plinth that reaches the height of the track bed and is lit by square, 4-pane windows located at the rear and northwestern end. The upper floor, which serves as the operating room, slightly jetties out on all sides and is marked by a sandstone band. It has continuous glazing on the front and ends, divided into windows with 4-over-4 panes separated by a single horizontal glazing bar, with four such windows on the front. The windows are late 20th-century replacements designed to match the originals. Access to the signal box is via a flight of stone-walled steps at the south-eastern end. The hipped roof has neatly mitred hips and is topped with tall terracotta pointed-ball finials. A chimney, located at the center of the rear wall, has been reduced in height but remains an architectural feature, projecting from the wall face with prominent quoining and supported by three corbels from the plinth.

Inside, the signal box retains a 1943 London Midland Railway lever frame with 35 levers, which was installed in 1957.
