Welcome to the UK's only 

Signalling & Telecommunications website.

 Thank you to everyone that has supported the site over the years.  

I left the S&T in 2020 and decided to keep the site running.

  Even though the site has always been free to use, it still costs me yearly to keep it going. 

I'm asking, if you can, to kindly contribute to the running costs and donate using the Paypal link below so I can keep the site open for as long as possible. 

Thank you to those who have contributed. 


The site contains technical documents and helpful information on a wide range of signalling equipment, some where no known notes exist. 

These documents are designed to help technicians digest the important information which is especially handy when travelling to a signalling fault for instance.

Please note that the site is dormant and is NOT updated. 

Created in 2009 to aid S&T technicians around the UK and wherever the same equipment is fitted in the World.


With 1000+ members Worldwide, it has hopefully helped countless of S&T technicians - please give me any feedback if its helped you!
