Telecommunications Heritage Group

About THG (and how to join)

What we do

Interests covered by the Telecommunications Heritage Group include old telephones, telegraphs, phone kiosks and other hardware. The complete heritage of telecommunications - civil, military, transport, public, private, ancient and modern, British and foreign - is studied across the membership. A number of members offer help on particular subjects such as kiosk restoration and railway telecommunications. Some enthusiasts own restored vehicles or telephone kiosks, whilst others are responsible for running complete multi-exchange telephone systems on preserved railways, using vintage telephone equipment.

Quite a few museums and preservation bodies have close links with the group and these can be discovered in the Days Out and Links sections.


The THG aims to educate future generations as to the marvellous inventions of the past and to retain knowledge and skills that might otherwise be lost while having some fun in the process.

THG members do collect obsolete exchange equipment and all kinds of telephones, telegraph and related apparatus but all of these are simply static exhibits without the vital knowledge, the processes and procedures of how and why they achieved what they did.

Our Publications

THG publishes four A4 sized Journals each year, packed with news and articles that are written by our members, for our members.


A growing number of THG members have joined CNet - this is a telephone network that uses an Asterisk Voice Over IP (VOIP) system and connects people up all over the world through their broadband connections.  Members have successfully connected old exchanges and equipment to the network, and in the UK we operate using the old STD codes.  See
