Half-Term Rail Closures to Disrupt Travel Plans Across Kent and South East London
Train passengers in south east London and Kent should prepare for significant disruption in early 2026, as major railway works will close several key lines around Dartford. From 14 to 22 February, Southeastern and Thameslink services will be suspended between Gravesend, Dartford, Crayford, Slade Green, and Barnehurst. Replacement buses will operate during this period. Additional closure dates include the weekends of 8–9 February, 1 March, and 5 April, to allow for necessary preparation and follow-up work.
The £10 million project at Dartford Junction focuses on modernising a heavily used part of the rail system. The planned upgrades include:
- Replacement of 10 track switches and crossings
- Installation of 400 yards of new rail and electrified conductor lines
- Platform adjustments at Dartford station to improve boarding access
The improvements are intended to boost safety and reliability, but carrying them out during the half-term break could lead to significant inconvenience for both regular passengers and holidaymakers.
We know there’s never a good time to do work like this, but we’ve deliberately chosen the half- term to minimise disruption, when schools are on holiday and fewer people are commuting. To make the most of the time available, we’ll also carry out additional improvement work at Dartford station.
Service suspensions will affect a large number of daily rail users, particularly those travelling for regional connections across south east London and north Kent. The closures are likely to lead to longer journey times, reduced frequency of connections, and increased pressure on replacement bus services. Rail operators have indicated that planning the works during the half-term period is intended to limit weekday disruption, though weekend travel will also be affected.
Passengers should expect delays, route changes and possible overcrowding on alternative services during the school break. Travel demand typically rises at this time, putting additional pressure on transport networks and replacement buses. With increased numbers of leisure and family travellers, capacity may be limited. Travellers are advised to review schedules ahead of time, plan for potential delays, and explore alternative routes where available.
While the engineering works aim to improve long-term service quality, the immediate impact will be felt most by leisure travelers relying on rail for short-distance regional trips. The February half-term often sees a rise in family travel, day outings, and local tourism, all of which will require extra planning this year. Revised train schedules and replacement bus information are expected to be released by mid-November to help travellers prepare for the planned service changes.
