Signal Box at Holywell Junction Railway Station

The Signal Box at Holywell Junction Railway Station is a Grade II listed building, part of the Chester to Holyhead railway, which aimed to enhance connections between London and Dublin. The railway bill was approved in July 1844, with Robert Stephenson as the engineer and Francis Thompson of Derby as the architect. Holywell station was opened in 1848.

This signal box is an LNWR type 4, produced from around 1880 until 1904, and it is one of the most popular designs of signal box ever made. The building is two storeys high and consists of five bays, topped with a slate roof. The gable ends feature pendants, finials, and flush bargeboards. The entire operating floor is weatherboarded and is illuminated by a continuous band of four-pane sliding sash windows. The long sides have cantilevered walkways supported by metal brackets, which return around the gable ends. There is a timber staircase at the southeast end. The lower storey is constructed of red brick and includes camber-headed four-pane windows and a doorway located beneath the stairs.
