The signal box was built in 1892 replacing an earlier box on the site. It was prefabricated in Derby as were all Midland Railway Company signal boxes, and believed to have been extended sometime to house more levers that were never installed. The construction is entirely of wood with no foundations. Concrete bases were not used until early in the 20th century. The signal box is a model 2a. It contains a 1906 Midland Railway tumbler interlocking lever frame. The earliest known photograph is of LMS1070 up stopping train leaving St Albans on 4th May 1946 - unless you have an earlier one.......? (see photo below!!)
