Commuters and airport passengers are facing major disruption on Tuesday morning after a fire next to the railway between Gatwick Airport and Purley blocked some lines, throwing Thameslink, Southern and Gatwick Express services into chaos.
The incident was first reported at around 8.49am on Tuesday 29 September. Trains through the affected stretch may be delayed, altered or cancelled, and passengers are being urged to check before they travel. The situation is live and developing, with the picture expected to change through the morning.
What we know so far
A fire next to the track was reported between Gatwick Airport and Purley on Tuesday morning. Some lines through the area are blocked, and as a result services may be delayed, altered or cancelled. The disruption is hitting three operators at once: Thameslink, Southern and Gatwick Express.
The early-morning timing means the incident is affecting both the commuter rush and travellers heading to and from one of the UK’s busiest airports. Anyone planning to use these routes on Tuesday should allow significantly more time and check live departure information before setting out.
Which services are affected
The blockage sits on a critical stretch of the Brighton Main Line, the artery connecting London with Gatwick Airport and the Sussex coast. All three affected operators — Thameslink, Southern and Gatwick Express — are run by Govia Thameslink Railway, which is why a single incident between Gatwick Airport and Purley can knock out airport express trains, Southern services to and from London Victoria, and Thameslink’s cross-London routes all at the same time.
Even once the fire is dealt with and lines reopen, passengers should expect knock-on delays and cancellations while trains and crews are got back into position. Services may also be altered at short notice — trains can terminate early, skip stops or be replaced by slower stopping services — so check your specific train rather than assuming the normal timetable applies.
Advice for affected passengers
If you have not yet set off, check live departure boards, the National Rail journey planner or your operator’s app before travelling. The incident is ongoing and the picture is changing quickly, so information from even an hour ago may be out of date. If your journey is not essential, consider delaying it until the disruption eases.
Know your rights. If you decide not to travel because your train is cancelled or severely delayed, you can get a full refund on an unused ticket from the retailer you bought it from — when disruption strikes, this applies to advance tickets as well as flexible ones. If you do travel and arrive late at your destination, keep your tickets and make a note of the service you intended to catch: you can usually claim compensation through the industry’s Delay Repay scheme.
Airport passengers in particular should build in plenty of extra time — a missed flight is far more costly than an early arrival at the terminal. If you are flying from Gatwick today, speak to your airline if the disruption means you might miss your flight, and keep receipts for any reasonable extra costs, as these can sometimes be claimed back depending on your travel insurance.
A familiar headache for London’s railways
Trackside fires have repeatedly brought parts of the capital’s network to a standstill — every train at London Victoria was halted by a track fire earlier this year. Southern passengers have also had a difficult run of it, with late-night trains scrapped all week across coast routes because of engineering work. And a fire that wrecked signalling at Clapham Junction recently threw Victoria services into chaos.
