Engineering works

Why planned engineering works can overrun and cause delays – and what we do to help prevent this

Whether we’re maintaining tracks and signals or replacing a bridge as part of larger scale engineering works, we do everything possible to keep disruption to a minimum.

The Scale of Our Network

The railway network has over 20,000 miles of track, 30,000 bridges and tunnels, and almost 6,000 level crossings. Trains run 24 hours a day, 365 days a year. The maintenance and engineering works that we carry out to ensure a safe and reliable rail network for passengers will always cause some disruption

Timing of Engineering Works

Most of our planned engineering work happens overnight and at weekends because this minimises disruption to passengers and keeps our workers safe. We are required by law to close a railway line before carrying out work on it.

When we need to change track layouts, update signalling systems, or do major engineering works, we plan for bank holidays. We close a section of the track for 24 hours. The railway is relatively quiet at this time. Although there is still some disruption, it affects fewer people.

Tt’s always a good idea to check before travelling on a bank holiday. Journeys can be planned online at National Rail Enquiries.

Preventing delays and responding if works overrun

  • Our engineering projects make the railway better. They let more trains run, help trains go faster, and make the network more reliable to reduce future delays. We plan these big projects carefully, often years in advance
  • When something goes wrong, we act quickly to assess the situation and finish the work so trains can run safely and on time again.
  • Sometimes, bad weather, machinery failure or unexpected complications cause a project to overrun. This doesn’t happen very often, but when it does, we work closely with the train companies to help keep passengers well served with information and provide options for a safe onward journey.
  • We know that when planned works overrun, passengers need clear, up-to-date information. We’re continually working on how we keep passengers updated when things do go wrong, because the works have to be completed before trains can run again.

We know it can be frustrating when engineering works cause a delay, but the reality is that overruns account for only a very small proportion of delays.
