Elsham Signal Box Approximately 10 Metres North East Of Level Crossing

Elsham Signal Box, located approximately 10 metres north-east of the level crossing, is a railway signal box built in 1885 for the Manchester, Sheffield and Lincolnshire Railway Company by the Railway Signal Company of Fazakerley, Liverpool. The structure features a timber frame that is weather-boarded, topped with a Welsh slate roof. It has a cast-iron lever frame and is rectangular in shape.

The signal box has entrances on the right return (east side) and a south front that faces the railway. It stands two storeys high with two bays. On the ground floor, there are two 4-pane casements with sills. The first floor has a plank walkway supported by cast-iron brackets, with an iron handrail beneath a full-width window that includes a row of single panes and a central 24-pane window, flanked by 4-pane sliding sashes at each end. The roof is swept and features ornate bargeboards and wooden finials, along with an iron stove-pipe chimney at the rear.

On the right return, there is a board door and a wooden staircase with plain treads, a single newel, and a handrail that leads to a landing supported by cast-iron brackets. This area includes an enclosed lean-to porch with an outer board door and a half-glazed inner door. The first floor has a hinged plank walkway on brackets with an iron handrail, similar to the front, and a 4-pane attic casement. The left return mirrors this design, with a similar plank walkway and first floor and attic windows, along with a 20th-century nameplate on the gable. The rear features a 4-pane casement overlooking the road.

Inside, the signal box retains its original 22-lever frame, operated from the first floor, with counterweights below that are inscribed with the manufacturer's name. An 8-spoke cast-iron wheel mounted on a pillar on the first floor operates the level crossing gates. This signal box is included as a representative example of the standard design used from 1881 to 1923 by the most successful signalling firm of the pre-grouping period.
