Mostyn No. 1 Signal Box

Mostyn No. 1 Signal Box is a type 4 signal box built by the London and North Western Railway, characteristic of those constructed between around 1880 and 1904, although this example is unusually tall. It features a gabled roof with pendants and finials at each apex over flush-set bargeboards, and has a slate roof that is now grouted. The entire operating floor is weatherboarded and illuminated by a nearly continuous band of four-pane sliding sash windows. On the southwest side, the glazing is arranged in five bays, with the second and fourth bays being wider. The northeast side has a cantilevered operating floor supported by brackets and lacks a central window; old photographs indicate that this side previously had a narrow bracketed walkway. Each gable displays a sign reading 'Mostyn'. The entrance is located on the southeast gable end, offset to the right, with a half-glazed door accessed by an open timber staircase. Below the operating floor, the structure is made of brown brick, standing two stories high with four windows on each side, featuring two tall recessed panels supported by header brick corbels. Segmental-headed four-pane windows are set into these panels, with higher first-floor windows on the northeast side. Although the footbridge has recently been demolished, the rubble stone base remains.
