Ferryside Signal Box is a Great Western Railway type 3 design, constructed in the 1880s and shown on the first edition Ordnance Survey 25in map of 1889. It has two storeys: the ground floor or locking room is built in brick, partly pebble dashed, and there is vertical timber boarding to the upper or operating floor with a continuously glazed gallery facing the railway track consisting of small paned windows, now replaced in uPVC but following the form of the original glazing. The gabled slate roof has eaves brackets and plain bargeboards. Still in use, the operating floor retains its 24-lever frame dating from 1898, block shelf, bells and track layout plan. The locking room below contains its locking apparatus intact.
