Urgent Track Repairs in Portsmouth Disrupt Travel Plans, Bus Replacements in Place

PORTSMOUTH, March 13, 2026 — Network Rail has announced an urgent series of track repairs to take place this Sunday, 15th March 2026, affecting train services between Havant, Fareham, and Portsmouth Harbour. The scheduled works, which will begin at 9 am, are essential for replacing two damaged wheel timbers on the Portcreek viaduct—a critical bridge that connects the mainland with Portsmouth on the Isle of Portsea.

Major Disruptions to Train Services

The upcoming repairs will result in significant disruptions to train services, as buses will replace trains on Sunday between Havant, Fareham, and Portsmouth Harbour. Passengers planning to travel in this region on the affected day will need to make alternative arrangements, as Network Rail engineers work to replace the damaged timbers on the viaduct.

Wheel timbers, which are large blocks of wood, are essential components of railway bridges, as they support the rails running over the structure. The replacement of these timbers is critical for ensuring the continued safety and smooth operation of the railway network in the area. Without these repairs, train services would face delays and could not operate at their usual speeds over the bridge.

As part of the ongoing work, the following alterations to train services will be in effect:

1. South Western Railway services to Portsmouth will be terminating at either Havant or Fareham, rather than continuing all the way to Portsmouth Harbour.
2. Southern services heading to Portsmouth will be terminating at Chichester, meaning passengers wishing to continue on to Portsmouth will need to use the bus replacement service.
3. Great Western Railway services heading to Portsmouth Harbour will be terminating at Southampton, further impacting the availability of direct train travel to Portsmouth on the day.

Bus Replacement Services

To minimize disruptions for passengers, bus replacement services will operate between Fareham and Portsmouth Harbour, as well as between Havant and Portsmouth Harbour. While the bus services will run throughout the day, it’s important to note that they will not follow a strict timetable. Passengers are advised to speak with station staff at their departure points for real-time information and assistance with their journeys.

In addition to the bus replacement services, passengers are strongly encouraged to allow extra time for their journeys, as delays are expected due to the nature of the work and the limited capacity of bus replacements compared to the usual train services.

Why Are the Repairs Necessary?

The Portcreek viaduct is an essential piece of infrastructure for the rail network, as it forms a critical link between Portsmouth and the mainland. The viaduct is used by several rail operators, including South Western Railway, Southern, and Great Western Railway, all of which provide important connections for both local commuters and long-distance travelers.

The wheel timbers being replaced were found to be damaged and in need of urgent attention to prevent further deterioration. Without replacement, the damaged timbers would have posed a safety risk, potentially disrupting the normal speed of trains and increasing the likelihood of delays. Network Rail has prioritized these repairs to ensure that train services can continue to run safely and efficiently for the long term.

George Murrell, Wessex Route Renewals Director at Network Rail, explained that these repairs are necessary to restore the bridge to full operational capacity. “We understand the inconvenience that this emergency repair work may cause to passengers in the Portsmouth area. These repairs to the wheel timbers are essential to ensure that trains can run at normal speeds again and to prevent further disruption to services in the future. We appreciate passengers’ patience and urge everyone to check for updates before they travel.”

Impact on Travelers and Customer Services

While Network Rail works to resolve the situation, passengers are advised to stay informed about the disruptions and plan ahead. Those traveling to Portsmouth on Sunday, 15th March, should anticipate longer travel times and possible delays due to the bus replacement services. Passengers are also encouraged to check their train times on Sunday morning via nationalrail.co.uk, as updates will be available on the site regarding the final adjustments to train schedules.

Customer Apology and Travel Advice

Jenny Saunders, Customer Service Director for Southern, also acknowledged the inconvenience caused by the repairs, emphasizing the importance of these works. “These damaged wooden blocks have been causing significant disruption to our passenger services, and it is absolutely essential that they are replaced as soon as possible. We apologize for the disruption, and we ask passengers to check for updates on their travel plans before Sunday. We understand that these changes will upset some travel schedules, but this repair is crucial for ensuring safe and efficient services in the future.”

Extra Measures for Affected Passengers

The importance of clear communication during these works is paramount, and Network Rail has encouraged passengers to allow extra time for their journeys. With the bus replacement service in place, the typical train travel time may be extended due to the use of buses and changes in route schedules.

Passengers are advised to:

1. Allow extra time for travel, particularly if planning to use bus replacements.
2. Check updated timetables and be prepared for delays.
3. Speak to station staff for guidance on bus replacement service timings.

Looking Ahead: Resumption of Regular Services

Regular train services are expected to resume as normal on Monday, 16th March 2026, when the repair work is completed. Trains will run as per the usual schedules, with services to Portsmouth Harbour returning to their regular routes. The bus replacement service will also cease once the repairs are fully completed.

Network Rail and South Western Railway have assured customers that despite this brief disruption, the train services will return to normal very soon. Passengers traveling to and from Portsmouth can look forward to a return to the usual level of service once the repairs are complete.

Flyers Get Ready For More Viable Travels

The urgent repairs being carried out on the Portcreek viaduct are vital for the continued safe operation of rail services to Portsmouth. Although these works will cause disruption on Sunday, 15th March, with buses replacing trains and some services being terminated at alternative stations, the repairs are necessary to ensure the long-term health of the rail network.

Passengers are advised to plan their journeys carefully, check for updates, and allow extra time for travel. With services set to resume normally on Monday, 16th March 2026, this short disruption will lead to smoother, more efficient travel in the future.
