Monks Siding Signal Box

Monks Siding Signal Box is a railway signal box built in 1875 for the London and North Western Railway, designed in the Type 3 style of 1874.

The structure features a brick base laid in English Bond, with a timber upper floor covered in horizontal weatherboarding. It has uPVC windows and a Welsh slate roof finished with grey hip and ridge tiles. The signal box is two storeys high and consists of two bays, topped with a hipped roof. The operating room is fully glazed at the front (north-west) and sides, with a single window at the rear that overlooks the approach to the nearby level crossing. The replacement windows do not match the original glazing pattern. Access to the operating floor is now via an external flight of steel steps located at the south-western end. The original entrance at the north-eastern end is indicated by a change in weatherboarding and a window with a raised sill. The door to the locking room remains in its original position below, featuring a segmental arched head made of brick headers. The two windows in the locking room that overlook the tracks also have similar arched heads and retain timber joinery with 4-pane fixed lights.

Inside, the signal box still has its original 20-lever London and North Western Railway Tumbler frame.
