25 Years of TfL: AJ Wells Proud to Be Part of London’s Journey

This year marks 25 years since Transport for London (TfL) was established, a major milestone in shaping a capital that is safer, more sustainable, and more connected. We’re proud to have played our part over the decades as TFL’s official supplier, helping define the look and feel of London’s infrastructure through signage and cladding that’s both robust and instantly recognisable. 

A trusted partner for nearly 30 years 

A.J Wells & Sons has worked alongside TfL for almost three decades as the official supplier of railway signage and cladding. From the early development of the Docklands Light Railway to the modernisation of the Underground and the opening of the Elizabeth line, we’ve supported the network with signage that is clear, consistent, fire safe and built to last. 

We’ve designed, manufactured and installed thousands of signs across the TfL network, playing a key role in keeping London moving. Projects include: 

  • Full re-signing of 40 DLR stations, including platform extensions ahead of the 2012 Olympics 
  • Bespoke signage for the Elizabeth line, screen-printed onto toughened glass 
  • Illuminated super graphics for London Overground stations, made with low-energy LED systems 
  • Creative commissions such as four PlayStation 5-themed roundels unveiled in 2020 
  • Key London Underground stations including Bank, Camden Town, Covent Garden and many more 

Made in Britain, built to last 

All signage is made at our factory on the Isle of Wight, home to our vitreous enamel plant (largest in the UK) and precision metal workshop. We use traditional techniques combined with modern technology to ensure each piece meets the highest possible standards. 

Vitreous enamel is created by fusing glass to steel at temperatures over 800°C. The result is a finish with exceptional depth and durability that is heat and weatherproof, colourfast and virtually maintenance-free. This is why it remains the preferred surface for the rail industry. 

Electric illuminated signs and roundels are also fabricated and hand-assembled in-house using low-energy LED components, delivering clarity, longevity and energy efficiency. 

A network that connects us all 

TfL has delivered remarkable improvements over the past 25 years. These include the launch of the Elizabeth line, the Night Tube, better step-free access, and a growing network of safe cycling routes. These developments have helped make London more liveable, more inclusive, and better connected. 

Our work may not always be in the spotlight, but it contributes to the everyday journeys of millions. We’re proud that our signage and cladding help create public environments that are clear, welcoming, safe and easy to navigate. 

Looking ahead 

We look forward to continuing our work with TfL, supporting the capital’s evolving transport infrastructure with quality, British-made design and manufacturing. 

Congratulations once again to TfL on this 25-year milestone. It’s a privilege to contribute to such a great city, and we’re excited for what comes next.
