Why is it important for TfL to preserve its digital history and retain documents for researchers to access?

I have come across a freedom of information (FOI) response on the Transport for London (TfL) website where they have started to remove pages and older documents from their website, which brings disappointment.

Here's what it states:

Request ID: FOI-0442-2627
Date published: 05 June 2026

"We do not keep publications on our website indefinitely and they may be removed when they are no longer current or accurate or have been superseded. The documents you refer to were from 2016 or before, and were removed in line with this. We do not plan to reinstate this information, and no longer hold the information formerly provided by the links you refer to."

The Issue: Digital Erasure, Link Rot, and Inaccessibility

I would dispute the assertion that the information from these documents is no longer accurate. While TfL may view older files as no longer current, they remain incredibly useful for researchers, enthusiasts, authors, and historians who need to review the context and provide accurate references.

When TfL deletes a PDF, it doesn't just disappear from their site; it breaks references across hundreds of academic papers, transport articles, Wikipedia pages, and planning documents. This is known as link rot, which severely damages the integrity of wider London historical research by breaking the digital trail.

Thankfully, some pages and documents referenced in the FOI request are on the Internet Archive's Wayback Machine. Unfortunately, not all the documents on the TfL and their predecessor website London Transport (LT) were saved. For me to find that the Department for Transport still has its 1996 strategy on improving transport in London, I had to do a deep search on the Wayback Machine to find it. People should not have to go through deep research on the Wayback Machine only to find a vital PDF document is missing entirely.



TfL does have their own Corporate Archives, including a dedicated website for digitised collections featuring previous editions of the London Transport News. However, that is not enough because researchers want to know what was happening behind the scenes involving TfL and LT.

According to the Corporate Archives policy, it states:

"3 Policy statement
3.1 All Information and Records created or acquired by TfL in the course of its business activities are the physical and intellectual property of TfL unless otherwise specified.
3.2 TfL recognises the collection, management and permanent Preservation of its Archives as a specific corporate obligation and information asset and will provide the necessary levels of organisational support and resources to ensure their survival and effectiveness.
3.3 With regard to the collection of Archives, TfL will adhere to the principles laid out in the Transport Act 1968 Section 144 as amended by the Railway Heritage Act 1996 and Greater London Authority Act 1999.
3.4 Information Governance will bring together responsibilities for Archives in all formats, including Digital Archives, from the creation and management of Records through to their selection and permanent Preservation and will encourage the exploitation of the Archives as a corporate resource."

In addition to this internal policy, public bodies have responsibilities under the Public Records Act 1958 and the Lord Chancellor's Code of Practice regarding the retention of records of historical value. The Local Government Association even has a dedicated guide on this topic providing an introduction to archives for councils.

I also checked the research guides on the TfL website via corporate archives, and they do not provide enough information, especially in regards to digital documents. Even the bus research guides completely omit information about the experimental XRM project from the 1970s, which is why I published an article about it.

A clear symptom of this issue is the unnecessary strain it puts on public administration. When the 2001 Mayor’s Transport Strategy vanished from the main website, a user actually had to file a formal statutory FOI request just to get a copy of the PDF because it was no longer easily accessible on the internet.

Furthermore, relying purely on physical records creates significant barriers. I am aware that The London Archives (by the City of London Corporation) and The National Archives hold physical documents in relation to transport in London.

However, accessing physical documents requires an appointment, travel costs, and time to visit the archive building. This is highly inconvenient for people who live far away from London, or even from another country where they have to apply for an electronic travel authorisation or a visa just to visit the UK.

While The National Archives do provide a digitisation service for their paper records, they are obliged to charge fees for research and record copying, making widespread digital access difficult.

Why Preserving This History is Vital

It is vital to provide this behind-the-scenes material to encourage more people to learn about the history of London Transport, especially regarding the development of landmark projects such as the New Routemaster, Crossrail (which currently directs to the archive wayback machine), and the Jubilee line extension.

When old digital documents are deleted, TfL loses its own history. Current staff might spend months researching a problem or planning a route, completely unaware that a team in 2012 or 2016 already did the exact same legwork. Preserving documents saves modern staff from reinventing the wheel. It also contextualises policy: understanding why a decision was made ten years ago helps current planners understand the constraints they are working under today.

Furthermore, keeping these documents publicly accessible directly benefits TfL's budget by easing the administrative and financial burden on compliance teams. It saves the general public, including researchers, from having to spend time making formal FOI requests simply to find a document. Crucially, this removes the statutory 20-working-day waiting time for the public, giving people immediate access to the relevant information they need precisely when they need it.

Instead of hiding these documents, it is best to promote them on social media to encourage public interaction. Transparency shouldn't just mean "what we are doing today". Showing the evolution of a project builds immense public trust. It proves to Londoners that transport planning is an evolving, thoughtful process.

When TfL shares its history, it turns everyday commuters into enthusiasts and advocates. Transport fans on social media frequently defend and promote TfL's vision; giving them the raw historical material keeps that community actively engaged.

As for physical documents, I do understand it takes time, resources, and specialist equipment to scan and digitise them. But for documents that already exist in digital formats, deleting them is an unnecessary step backward.

Examples of Valuable Historical Material

Showing the evolution of older express bus concepts highlights why old information is gold. For example, I previously advocated for TfL to use the proposed Speedbus from over 50 years ago (1973) with ideas for new express bus routes, which directly mirror what we see today in the Superloop bus network.

Here are some of the historical digital documents I have previously highlighted on social media to keep this history alive:

Fit for the Future


Prospective London Overground services (2016 Rail Vision Map)

But hey, TfL, you could revive your 2016 proposal to expand the management of suburban rail services in Greater London. You should also include the Greenford Branch line, as it falls within Greater London. 🙂 web.archive.org/web/20161013...

Transit schemes proposals from the 2000s (Most never left the drawing board, while some now form part of the Superloop express bus network)


Proposed Solutions

I suggest that there should be a dedicated website for TfL, the Greater London Authority, and potentially others to allow researchers, enthusiasts, and authors to find the documents they need for an upcoming article, book, or report.

Alternatively, this could be achieved by introducing a low-cost 'archive.tfl.gov.uk' subdomain with a prominent "historical context only" disclaimer to prevent any public confusion.
Precedents and Opportunities

Another excellent external model is the Railways Archive, which hosts digitised historical documents and relies on donations to run the service. As you can see in my social media post below, I previously shared four maps from an old study conducted by the Department of Transport, London Regional Transport, and British Rail using these types of resources.

Other London bodies, such as the London Assembly and London TravelWatch, have successfully preserved some of their older documents online.

Look at the example set by Córas Iompair Éireann (CIÉ) in Ireland. They have digitised and published historic annual reports directly on their website. This is certainly something TfL has missed out on, as TfL’s online annual reports only go as far back as 2003 and completely ignore historical predecessors like London Regional Transport (LRT) and the London Transport Board.

Most important of all, 16 September 2026 will mark exactly 30 years since the London Transport website was launched. This major milestone is an important moment for TfL to take note of and celebrate as part of its digital history.


Conclusion

Preserving digital history is not about living in the past; it is about protecting the foundation of London's future transport network. By safeguarding these records, TfL can support its modern staff, alleviate the strain on public administration, and build lasting trust with the community it serves. As the 30th anniversary of its digital presence approaches, TfL has a unique opportunity to lead by example—proving that open transparency and historical preservation go hand in hand.
