Blankney Signal Box

Blankney Signal Box is a Grade II listed Great Northern Railway Type 4 signal box, built in 1928 by the London & North Eastern Railway Company. It is constructed of brick and features a slate-covered roof, with a later projection for the operations room.

The exterior of the signal box has a rectangular plan and a pitched slate-covered roof, adorned with timber bargeboards and finials. The operations room also has a pitched roof with matching bargeboards and a finial. At the base of the box is a deep brick plinth, with brickwork above. The operations room is largely glazed, featuring replacement window frames that mimic the original Yorkshire sashes. These windows run continuously along the north-east side, the south-east gable end, and part of the south-west side. The north-east elevation includes two windows under segmental arches in the locking room, which appear to be original. Access to the operations room is via metal steps at the north-west gable end, while the locking room door is located at the south-east gable end. Marks in the brickwork beneath the windows at the south-east end indicate where brackets once supported a walkway, and these brackets remain in place at the north-west gable end, supporting the timber projection.

Inside, the signal box retains its original frame. In the locking room, there is a circular cast-iron plate with a raised design that includes the words "SAXBY & FARMER PATENTEES LONDON" and the company crest, suggesting it may be a second-hand example; however, it is alternatively identified as a Tyer Direct Tappett frame. The operations room features a cast-iron wheel with a handle, connected to a cast-iron frame, which operates the opening of the crossing gates. The room is open to the roof, revealing rafters and collars, as it is not ceiled.
