Nunthorpe Signal Box

This railway signal box was built in 1903 by the North Eastern Railway. It is a Type C2b design from 1899. The signal box is constructed of red brick in English Garden Wall bond, with a timber porch and steps leading to the upper operating floor, and has a Welsh slate roof. It is two storeys high, with two bays, and is orientated parallel to the tracks on its north-eastern side. The roof is hipped with small gablets fitted with ventilation louvers. Originally, the upper operating room was fully glazed to the front and gable ends, but two sections of the front have now been boarded over following the replacement of the windows with double-glazed units around 2011. These modern windows replicate the original glazing pattern, incorporating horizontal sliding sashes to the front and gables. The space above the windows to the eaves is filled by diagonally set timber boarding, along with the principal timber framing to the windows, both of which are considered original. The rear of the signal box is entirely brick-built and features one replacement window overlooking the road approaching the crossing. A timber porch with a hipped roof and a dog-legged flight of timber steps provides access to the upper operating room, and is an original feature. A door to the ground-floor locking room is located below the porch. The two original windows in the locking room, which previously looked towards the tracks, have been bricked up. External balconies, designed for cleaning the operating room windows, are present in the form of planked walkways supported on iron brackets, with iron handrails extending upwards. Inside, the signal box retains a Westinghouse frame with 16 levers, a ship's wheel mechanism for manually opening the level crossing gates, and a Tyer and Co electrical mechanical block instrument.
