HISTORY

The signal box was built in June 1892 by the Midland Railway, replacing an earlier box on the site, when the line was expanded from two to four tracks southwards.

The box is classified by the Signalling Record Society as a Midland Railway 'Type 2A' and is one of many made from parts pre-fabricated in Derby. It is of wooden construction with a slate roof and heavy glazed windows. It had no foundations until the recent restoration!

The Midland Railway 44 lever ‘Tumbler interlocked' frame controlled all the trains on the four tracks between between Harpenden and Napsbury.

The frame was reconfigured when the track or signalling changed, e.g. with the introduction of slow and fast line working southwards in 1895 and northwards in 1906, and in 1970 when St Albans North box was closed. The box itself was altered in 1963 when a toilet was added. It was listed Grade II in 1979 just before closure in early 1980.
