Hope Junction Signal Box, later renamed Penyffordd, was a Railway Signal Co. design, erected in 1885 when the main line track was doubled and block working introduced on the Wrexham Mold and Connah's Quay Railway between Shotton and Wexham. It is a two-storey structure, set to the north of the west (Connah's Quay-bound) platform of Penyffordd Station (nprn 41400), of all-timber horizontal weatherboarded construction under a pitched slated roof, with an external wooden access stairway at the south end. The building had decorated bargeboards and roof finials and the typical RSCo. feature of a four-light window set high in each gable. The RSCo. frame originally had fifteen working levers and nine spare.
