Signal Box at Caersws Railway Station

The signal box at Caersws Railway Station is a small timber structure built on a low blue brick basement. It originally had a slate roof, which has since been replaced with corrugated iron. Access to the box is via an external timber stair from the platform on the northwest side, leading to a hooded glazed door at the top. The front and southeast gable end feature small-pane horizontally sliding windows that offer views along the railway line. A name board is positioned at the center, and the gable end has bargeboards with decorative undulating ornament, along with timber finials and pendants. The eaves overhang, and there is a red brick chimney.

Nearby, approximately 250 meters to the south, is an upper quadrant LMS pattern signal gantry, and about 85 meters to the north is a GWR pattern gantry with home and distant lower-quadrant semaphore signals.

This signal box is notable for retaining its original Dutton 18-lever frame, of which only four levers are currently in operation. These control the semaphore signals above and below the box and lock the crossing gates. The token box was removed in 1988.
