Working by the railway?

The rail network is divided into a number of geographical routes and High Speed 1. If you are planning on doing any work near the railway please contact your local ASPRO team who are your gateway to supporting you in delivering your work safely.

Working near the railway can be a dangerous environment and we are in a position to help you navigate the risks. Network Rail is committed to safety so we want to help you deliver your works safely and securely.

To help you achieve your time frames please contact us as early as possible in your planning process, this will enable us to best support you in delivering successfully.

The ASPRO teams can help you with a multitude of works including:

  • construction sites near the railway
  • utility works (water, electric, gas, cabling etc.)
  • radio transmitters
  • bridge works
  • domestic maintenance (e.g. roof, scaffolding, building repair and maintenance)
  • new road schemes
  • inspection and surveying
  • works within the designated precautionary area of level crossings
  • domestic related projects (e.g. house extension) under domestic maintenance (e.g. roof, scaffolding, building repair and maintenance)

Asset protection and optimisation management of third party works on Network Rail Infrastructure

To support the mitigation of potential risks to the railway when third party organisations work on or near the infrastructure, we have made the standard more readily available. You can download the standard ‘asset protection and optimisation management of third party works on Network Rail infrastructure’ from our downloads for third parties page. This standard applies to third party works being undertaken where Network Rail is not the sole client, including the asset protection assurance of works being undertaken by a third party, to assets that will be taken over by Network Rail for operation and/or maintenance.

ASPRO do not deal with emergency works. For emergencies, contact:

There are other specialist teams within Network Rail that cover the areas listed below:

Managing risk to the network

Working by the railway can be both a risk to your works and our infrastructure. We are keen to work in collaboration with all our customers and lineside neighbours to safeguard you and the railway.

We’ve looked at 41 separate categories of risk that could cause problems, delays or extra cost to a project on the railway and analysed where Network Rail can take ownership of that risk, or made it clear who will cover it. An ‘industry risk fund’ has been established to enable Network Rail to take the risk and fund liabilities when projects encounter certain unforeseen industry related problems. The default risk allocation table is available from our downloads for third parties page and details each potential risk and who is responsible for it – Network Rail, the industry risk fund, the sponsoring customer or the enhancement contractor.

Our ASPRO teams advise on the potential impact of different kinds of work including construction, maintenance and work near level crossings. They can visit you on site and give advice at meetings.

Open for Business

Team briefing taking place on a work site.

We are making it easier for other organisations to invest in and build on the railway. As we become more open for business, we are reviewing and amending our standards, practices and approach to risk management, streamlining processes to make it easier to work with us. Reforms to our ASPRO organisation so far include: new leadership roles, a national framework, service level commitments, customer satisfaction surveys and risk clarification.

Give us feedback – customer satisfaction surveys

As Network Rail owns and operates Britain's railway, our responsibility to run and maintain it safely can mean other organisations feel we are difficult to work with when delivering railway projects. Recognising this, we are implementing a number of reforms to break down barriers and make it easier to work with us.

To ensure we're making the right changes, we've started conducting customer satisfaction surveys with third parties we work with and have committed to regularly reporting on the results.

If you've worked with Network Rail's asset protection and optimisation teams and would like to give us feedback, please complete our customer satisfaction survey.

The results from our latest customer satisfaction survey can be found on our downloads for third parties page

External parties we work with

An organisation other than Network Rail intending to undertake works which will physically change and potentially benefit the operation, assets, design or other functionality of Network Rail’s infrastructure.

Third parties may include train, freight and station operators, local Passenger Transport Executives, the Department of Transport (DfT), DBFO, PFI, or commercial developers etc.

Examples of third party works may include:

  • Localised schemes (e.g. new siding connected to an existing line, changes to existing depots/stations, and where there is a consequential alteration to Network Rail’s managed infrastructure) funded and undertaken by a train operator.
  • Schemes (e.g. new stations/depots) funded and undertaken by a local Passenger Transport Executive (PTE) or county council, or private developer where the assets created will be managed and operated by Network Rail under its health and safety management System.
  • Nationally significant schemes (e.g. main line upgrade) funded and specified by the DfT, Transport Scotland or the Welsh Assembly under development or framework agreements with those parties, and/or their nominees.

Related links:

An individual, member of the public or organisation other than Network Rail which promotes, funds, designs, constructs, owns and maintains the works that are within close proximity to the railway but do not physically change the operation of railway infrastructure and will interface with the railway infrastructure.

However, they may also require incidental changes to Network Rail infrastructure such as

Outside parties may include local authorities, statutory undertakers, builders and private owners.

Examples of outside party works may include:

  • An adjacent landowner working within their own property boundary, which may include works to the property boundary.
  • The relevant Highways Authority building a road bridge over the railway in accordance with an Air Rights provision and a Bridge Agreement.
  • A utility company installing an undertrack crossing in accordance with a wayleave to carry a main sewer.

Other useful information

The Highways Interface team work closely with the Asset Protection & Optimisation team to provide specialist advice. They deal with technical and administrative issues related to the New Roads and Street Works Act (NRSWA) 1991 and related legislation.

Their duties cover the Exchange of Works information and the provision and maintenance of information for the National Street Gazetteer. They also represent Network Rail on the Joint Authorities Group (JAG UK) Highways Authorities and Utilities Committees (HAUCs) in England and Wales, and Roads Authorities and Utilities Committees (RAUCs) in Scotland.

All works notices under NRSWA are issued through Street Manager in England, ETON (Electronic Transfer of Notices) in Wales and the SRWR (Scottish Road Works Register) in Scotland.

Working by the High Speed 1 line

The High Speed 1 (HS1) railway is different from the rest of the network in that Network Rail (High Speed) operates and maintains it on behalf of HS1. They follow the Network Rail (High Speed 1) Outside Parties Team Charter. If you’re planning work near HS1, you’ll need to complete an infrastructure search request form. We can help by telling you about:

  • historic or as-built structures
  • HS1 property boundaries
  • any HS1 buried services in the area.

Our outside parties team is committed to giving advice and managing the impact from outside party works. See our Development handbook. If your business borders HS1, see our Working together leaflet and Working together poster.

Whilst we accept that graffiti can be unpleasant, the cost of removal can often be high. As a public body we have to adhere to the Government’s Managing Public Money principles and prioritise our expenditure on safety critical matters and those affecting the operation of the railway. For those cases that involve offensive graffiti, we will do all we can to remove this within 24 hours. Visit our community pages to find out the best way to report graffiti and vandalism. 

Our vegetation management work is essential for safety, and we do everything we can to keep local residents up to date. We need to manage vegetation next to the railway throughout the year to remove any safety risks while being sensitive to wildlife and the local environment. Visit our environment pages to find out why we need to manage vegetation and how it is done.
