Major Rail Works Continue Over the Weekend: How to Navigate the M25 and A3 Disruptions

In January 2026, Network Rail has announced that major rail improvement works will continue for a second consecutive weekend on one of the UK’s busiest rail lines. These improvements affect several key routes, including the lines between Brighton, Gatwick Airport, and East Croydon, as well as the connections between Reigate and Redhill and Redhill to Tonbridge. The works are part of a broader effort to enhance the safety and efficiency of the rail network, though they are expected to cause disruptions for both commuters and tourists this weekend.

For business travelers and tourists planning to travel across these routes, it is essential to plan ahead and consider alternative travel options due to the ongoing closures and service diversions.

1. Details of the Ongoing Railway Works

The improvements are being carried out during what is typically a quieter time of year for the railway system, as Network Rail looks to avoid disrupting services during peak travel periods. The main work involves the replacement of rails and conductor rails, refurbishment of switches and crossings, and the installation of new electric conductor rails in areas like Redhill to Reigate.

Other key improvements include:

• Replacement of track between Purley, Earlswood, Horley, Merstham, and Coulsdon South.
• Drainage system repairs across three miles of track at Caterham to improve water management and reduce potential delays.
• Installation of wheel timbers at Godstone and Coulsdon South to enhance the structural integrity of key bridges.

2. Impact on Business and Tourist Travel

For business travelers, the train delays and diversions could lead to extended journey times, especially for those traveling to or from Gatwick Airport or Central London. Delays may cause missed meetings, appointments, or connections. Passengers flying out of Gatwick or arriving in London need to account for potential rail disruptions and plan additional time for their trips.

Tourists visiting London or the South East may also face delays. While the diversions provide alternative transport options like replacement buses, the overall travel time may increase, especially if travelers are unfamiliar with the detours. For tourists aiming to visit Brighton or Croydon, understanding the revised schedules and alternate routes is crucial for avoiding frustration.

Business travelers and tourists alike can expect:

• Train services affected on Saturday, January 14, and Sunday, January 15, 2026.
• Alternative transport options available, such as replacement buses and rerouted services.
• Potential delays to Gatwick Airport connections and onward travel from London.

3. What You Need to Know About the Works: A Step-by-Step Guide

If you’re traveling between Brighton, Gatwick, or East Croydon, follow these steps to avoid disruptions:

1. Check Your Train Service:

Before setting out, check real-time updates from National Rail or the Southern Railway website for the latest information on service disruptions or delays.

2. Use Replacement Bus Services:

For trains that are diverted, replacement buses will be available. These buses will take you around the closed sections of the rail line. Be prepared for longer journey times as buses may take alternate routes.

3. Plan Extra Time for Travel:

Especially if you are heading to Gatwick Airport, allow extra time for delays caused by the diversions. If you’re on a tight schedule, consider taking alternative transport options like the Elizabeth Line or London Underground.

4. Check Parking Availability:

For travelers arriving at Dore and Totley Station, or if you plan to park at Gatwick, check in advance for any changes to parking facilities and to ensure space availability.

5. Consider Alternative Routes:

If you’re traveling between Brighton and London, consider using other routes, such as the M23 or A23, if road traffic conditions allow.

4. Further Disruptions Expected

The rail improvement works are scheduled to continue into the next weekend, January 21-22, 2026, with further disruptions expected on routes between Reigate and Redhill. Additional engineering works will begin on February 1, with ongoing developments scheduled for the coming months.

Travelers are encouraged to stay updated on future works by checking with Network Rail and train operators for any new disruptions.

Key Points to Note for Travelers:

• Two-day disruption on the A3 and A23 corridors in January.
• Replacement bus services in place, but expect longer travel times.
• Extra precautions advised for business and leisure travelers who need to reach London or Gatwick.
• Alternative routes available for car travelers, but plan for possible delays.

5. Practical Tips for Travelers

• Check train schedules in advance: Always check the latest updates for delays and service changes before traveling.
• Consider alternative routes: If the A3 or A23 is closed, B roads might be less affected, so plan your route accordingly.
• Give extra time: For those heading to Gatwick Airport, allow extra time for the train delays or opt for replacement buses.
• Monitor social media: Follow Network Rail and Southern Rail on social media for immediate updates on travel disruptions.
• Stay informed: If traveling in the south of England over the next few months, make sure to stay informed about engineering work schedules and future changes.

Conclusion

The A3 rail disruption caused by bridge replacement works and other infrastructure upgrades in the Brighton to Gatwick corridor is set to impact travelers for at least two weekends in January 2026. Both business and tourist travelers should prepare for delays and plan alternative routes accordingly. With replacement buses and diverted train routes, it’s crucial to keep up to date with real-time information and allow extra time for your journeys. With ongoing improvements to the UK’s rail network, travelers can look forward to a more efficient and sustainable travel experience in the near future.
