Thorpe Culvert signal box was constructed by NewtworK Rail in

2003. English Heritage stipulated that the structure should replicate the GNR building that it was replacing. Looking at this, it seems that Network Rail did a reasonable job both in the design and the building materials used. Incidentally, the original box, that was on exactly the same spot, needed replacement as it was in a structurally precarious condition and needed demolition. At the same time the box was rebuilt, the opportunity was taken to replace the semaphores with colour lights and to install barriers at the level crossing.
