Passengers travelling by train in Essex and Suffolk face a month of weekend disruption in November, as engineers carry out track renewals, station upgrades and preparatory work ahead of major Christmas engineering works. Replacement buses will run on the affected routes, but the closures change from weekend to weekend — and one Suffolk town loses all of its trains for four days in a row.

The programme is being delivered by GBR Anglia, the unified structure that brings together c2c, Greater Anglia and Network Rail Anglia. It covers three weekends — 14 and 15, 21 and 22, and 28 and 29 November — alongside a separate four-day closure at Lowestoft. Here is what is closed, when, and how to travel instead.

Weekend by weekend: what is closed and when

Saturday 14 and Sunday 15 November: buses replace trains between Sudbury and Marks Tey all weekend. On Sunday only, buses also replace trains between Ipswich and Colchester and between Manningtree and Harwich Town. Trains continue to run between Norwich and Ipswich, and between Colchester and London Liverpool Street.

Saturday 21 and Sunday 22 November: buses replace trains between Braintree and Witham, and again between Sudbury and Marks Tey. On Sunday only, buses replace trains between Colchester and Ingatestone for journeys to and from London, and between Colchester and Chelmsford for intermediate journeys. Trains continue between Norwich and Clacton-on-Sea and Colchester Town, and between Chelmsford and Liverpool Street via Ingatestone, connecting with the replacement buses.

Saturday 28 and Sunday 29 November: buses replace trains between Ingatestone and Southend Victoria and Newbury Park, a London Underground Central line station, with tickets accepted between Newbury Park and Stratford or Liverpool Street. Buses also replace trains between Southminster and Wickford. Trains continue between Norwich, Ipswich and Clacton and Shenfield, via Ingatestone, connecting with the buses.

Lowestoft: no trains for four days, 13–16 November

The longest single closure falls outside the weekend programme. From Friday 13 to Monday 16 November there will be no train services between Lowestoft and Norwich, or between Lowestoft and Ipswich, while engineers replace the track at the station's platforms 2 and 3.

The track there is 50 years old, and the ground beneath the rails is saturated in several places, which makes faults more likely. A special vacuum machine will remove the old ballast before fresh material is laid, and some sleepers and rails within the platforms will also be renewed.

For the four days, buses will replace trains between Lowestoft and Norwich, Lowestoft and Oulton Broad South, and Reedham and Lingwood via Cantley. On Friday and Monday only, buses will also run between Lowestoft and Haddiscoe. Trains between Ipswich and Oulton Broad South, and between Norwich and Great Yarmouth, will run as normal.

Joe Kennedy, Infrastructure Director for GBR Anglia, said: "The vital work we're doing in November will help us provide the best possible service on these busy and important routes for years to come. We're really sorry for the disruption, especially on the two weekdays, but this is a big job that we must get done to maintain a reliable railway."

What is already finished: Saxmundham junction

Not all of November's news is disruption. Network Rail has completed the renewal of Saxmundham junction on the East Suffolk Line after a nine-day closure from 24 October to 1 November, and Greater Anglia services between Halesworth and Ipswich resumed on Tuesday 3 November.

Engineers converted the junction, about half a mile north of Saxmundham station, from manual to powered operation and installed modern equipment to improve its flexibility and performance. The work also included signalling improvements along the route.

The junction is where the Leiston branch line splits from the East Suffolk Line, and it is a key part of the plan to move construction materials for the Sizewell C nuclear power station by rail. Around 60 per cent of the materials for the project are due to be delivered by rail and sea, and the first commercial freight train reached the Sizewell C site in September.

Limehouse platform closure extended to 23 November

London-bound passengers on c2c services from Essex face a longer wait at Limehouse, where Platform 1 will now stay closed until 04:40 on Monday 23 November. The closure was extended after the freight train derailment at Barking on 23 October, which forced the line through the station to be reopened for passenger services while platform renewal work continued.

Passengers who would normally use the London-bound platform are advised to take an Essex-bound train to West Ham and connect with c2c services there, or to use London Underground services to Tower Hill. The work replaces the platform's timber decking with a modern glass-reinforced plastic composite system.

Why the work is happening

The November programme includes a £1 million platform renewal at Bures station, with a full replacement of the platform deck, along with rerailing and track maintenance at Marks Tey and Kelvedon, and maintenance on the Harwich Town branch line, including replacing wheel timbers, vegetation management and tamping. Bures station and its car park will be closed from Saturday 21 November until 04:00 on Monday 23 November.

Engineers are also carrying out preparatory work on the Great Eastern Main Line ahead of major Christmas track renewals at Forest Gate and Stratford, and general maintenance on the Southend Victoria and Southminster lines. Martin Beable, chief operating officer for GBR Anglia, said the projects were part of ongoing investment in a safer and more reliable railway, and thanked passengers for their patience.

How to plan around it

Passengers should check their journey at greateranglia.co.uk or nationalrail.co.uk before travelling, and allow extra time. Replacement buses do not always follow the same stopping pattern or journey time as the trains they replace, and some routes are affected on one weekend but not another. Anyone travelling to a London terminal, or changing at Ipswich, should confirm both legs of the journey.
