Keighley Junction Signal Box Approximately 10 Metres to North-West of Bridge Over Railway

Keighley Junction Signal Box, built in 1884 for the Midland Railway Company, is located approximately 10 metres to the north-west of the bridge over the railway. This two-storey, single-cell structure features a timber Welsh slate roof and measures two bays by one bay. The ground floor is vertically boarded, while the first floor has vertical boarding and glazing, with window frames that have angled top corners. The signal box is supported by large angle posts, and the narrow intermediate posts on the first floor are chamfered.

The eaves board is prominent, and the hipped oversailing roof is adorned with two wooden finials, one of which is missing its top. The north-west end has a boarded door at ground level, with wooden steps leading up to a first-floor doorway that is flanked by two 4-pane windows on the left and one on the right. The right side features one 4-pane window on the first floor to the left and a small inserted window to the right. The left side, which faces the main line, has an entirely glazed first floor with two pairs of large sliding sashes that include glazing bars. Below this is a board that is lettered "Keighley Station Junction." The rear of the building has an added out-shut that masks the ground floor, while the first floor has a wide side-sliding sash with glazing bars.

Inside, the ground floor contains mechanical relays operated from the upper room, which is connected by levers. The tipper room has a full range of signal levers on one side, with a bracketed shelf above that holds block instruments and bells, including one old bell. There is also an old wooden bench-locker, and the space was originally heated by a coal grate, later replaced by a Romesse stove, although the flue hole has been blocked up. This signal box is of the Midland Type 2a design, known for being one of the most common signal box types, and it is noted that it may soon become the oldest surviving Midland box.
