Leighton Buzzard No.2 SC had an unusual extension at the South end. Can anyone say what was its purpose?

Leighton Buzzard No. 1 signal cabin (Not No. 2!) Annexe

Philip, Hello.
Your question comes at quite a timely moment in several ways. The answer lies 100 years ago and the context is covered in the 100 years ago section of the Society’s new book ‘Forty Years of the London & North Western Railway Society’. Following a review of the working of the line in 1912 (See the Society Journal for June 2013 – the article on the Central Timing Office), the LNWR began to introduce a Train Control system at the end of 1912. The majority of the work was done in 1913 (see page 54 of our book). This was based on the system which had been successfully pioneered by the Midland Railway and involved the establishment of Control Offices at strategic locations to oversee train operations in the area.

The introduction of Control Offices involved the provision of additional telephone circuits between the new Control Offices and key signal boxes stations and yards. At a few boxes it was considered that the extra work would overload the signalmen and distract them from their work. In these cases a new telephone operator’s position was created. To make space for the operator, in a few cases new ‘telephone annexes’ were constructed to house them. Although placed at the box to ensure direct contact with the signalmen, to minimise distraction to the signalling work these annexes were created as a separate room! The extension at the near end in your photo of Leighton No.1 is one of these, and as you can see, it has its own entrance door. There was another annexe at Tamworth No. 2 signal box, but there, although a separate room, the operator could only access it by walking through the box as it was at the opposite end of the box to the entrance door!
This was not the only extension to Leighton No. 1 signal box. There was a conventional extension on the far end of the box, which can be distinguished in the photograph. This was done in 1927 to house an extension to the lever frame.
I hope this helps.
Richard Foster.

I agree with everything written by Richard!

Article in preparation on the LNWR Control system ...

In 1927 the box and the lever frame were extended to provide for the Fast /Slow double junction installed at that time. It was one of 6 new junctions installed after the ex-MR senior officers were appalled to find that trains could go to or from the Slow lines only at Watford Junction, Tring, Bletchley or Roade and nowhere in between!

Another article in preparation ...
