Two people were hurt when a train derailed near Watford Junction after torrential rain caused a landslide at the mouth of a tunnel.

The 06:19 BST service from Milton Keynes to Euston left the track at about 07:00, Network Rail said.

Part of the train derailed and was clipped by another. The fire service helped evacuate almost 400 passengers.

London Midland has warned that delays will run into the weekend with many services cancelled out of Euston.

One traveller was treated for a neck injury and the other for chest pain.

A Virgin train was sent to the scene to take stranded passengers on to King's Langley, Hemel Hempstead and Milton Keynes.

London Midland and Virgin services remain "severely disrupted" from the Midlands, the north-west and Scotland.

Passengers' stories

Jessica Long, a passenger on the derailed train, said: "The train hit something, it went up into the air a little bit and went off the track. You could hear it going over the gravel.

"When we stopped, we checked everyone on the train was OK, and then the next thing we knew we got hit by another train so we were absolutely panicking.

"The way the train driver reacted, like, that guy deserves an absolute medal because he did so well. He came straight on the Tannoy to ask if we were all ok and tell us what was happening.

"Hats off to that guy, and he was injured as well."

Passenger Clive Todd was commuting into London from Hemel Hempstead on the same train when he heard an "almighty noise".

The train "shuddered" and then came to a "quick halt" as it derailed, he said.

Mr Todd said he was a few carriages away from where the train came off the tracks, but he could see part of it "at a right angle".

The experience was "scary stuff", he said.

Jack Burgess was a passenger on the 06:34 London Euston to Birmingham New Street train, which clipped the derailed train.

He said: "Around 7am we went through the tunnel near Watford and there was a really loud scraping noise against the side of the train that got louder and louder, and then a very loud thud, which made the train bounce up and down a lot.

"The train then stopped and the driver got on the intercom, sounding very panicky.

"He kept telling everyone to stay in their seats. We were stationary for four hours or so.

"I just got off a train at Milton Keynes and they're not letting me go to Birmingham."

Martin Frobisher, route managing director for Network Rail, said: "A train hit a landslip, caused by torrential rain, resulting in a small section of the train to leave the tracks a few miles north of Watford today. The train remained upright and there are no reported passenger injuries.

"A short time, after another train heading north gave a glancing blow with the derailed train. The train heading north did not leave the tracks."

Francis Thomas, from London Midland, said the accident happened on a "busy stretch" of track, and "if something goes wrong it will take a long time for services to get back to normal".

Network Rail said two of the lines had reopened at reduced speed through the affected area, but journeys were expected to be delayed by up to 60 minutes.

"The two trains are still in the tunnel and Network Rail can't assess the damage to the track until they are moved," Mr Thomas said.

"They are unlikely to be moved until Saturday morning "at the earliest."

By Richard Westcott, BBC Transport Correspondent

There are 9,600 miles of embankments and cuttings above 3m high on Britain's rail network and most of it was built 150 years ago.

An engineer told me that when the Victorians knocked them up, they basically piled them as steeply as they could, using materials that they'd just dug out of cuttings further down the track. Some of that material deals with water about as well as a woollen swimsuit, so small sections can be prone to slipping after a downpour.

Network Rail does check railway cuttings and embankments every year, looking for cracks, bulges, or lose soil; but frankly, it's hard to work out which bits are about to fail and there's an awful lot of it.

When they fix embankments they make them shallower and they use modern materials, including different grained sands that drain the water yet lock together so they don't slip.

Another weather problem comes from the trees. You may have noticed in recent years, gale force winds keep blowing them onto the lines.

The old steam engines used to set fire to the branches, which kept them back. Today they often grow unchecked.
