Signal Box: Liverpool Street London Underground

MATERIALS: locking room of yellow stock brick in Flemish bond. Operations room is timber-framed with dado-height vertical weatherboarding and timber-framed horizontally-sliding sash windows. Hipped slate roof has overhanging eaves supported by curved timber brackets.

PLAN: two storeys with the operations room two bays long by a single bay wide.

EXTERIOR: located at the western end of the northern Metropolitan and Circle line platform. Low locking room with three blocked round-arched openings facing the track partly encased by later extension of the platform. The upper, timber-framed, operations room has glazing on all four elevations. This was because a short lived spur, the tunnel for which can be made out in the headwall behind the signal box, originally ran into the Great Eastern Railway’s station. The windows are six-pane, timber, horizontal sliding sash windows. Above the windows are panels with cut-out quatrefoil decoration. The operations room has entrances at both ends with glazed six-pane doors reached via modern steel steps. On the southern elevation is a folding timber ledge on steel brackets allowing for window cleaning. At the north-east corner the signal box is connected to the headwall of the station via a brick flue for the fireplace.

INTERIOR: the interior has dado matchboard panelling, boarded ceiling, fitted cupboards at the west end and original fire surround at north-east corner. It retains the 1954,15 lever Westinghouse Brake and Saxby frame and control panel. The locking room was not inspected.
