The injuries reported are “minor” and the driver of the train is in “shock”, according to Network Rail.
Ellie Burrows, Network Rail’s route director for Anglia, said: “At approximately 8.20am a train hit the buffer stops at Enfield Town at slow speed.
“The driver is being treated for shock and there are reports of a few minor injuries.
“Emergency services including the British Transport Police are on site and an investigation is under way.”
Around 50 people were evacuated from the train, with station staff helping passengers off the carriages before the London Fire Brigade (LFB) attended.
A London Ambulance Service spokeswoman said: “We were called at 8.16am this morning to reports of a train derailed at Enfield Town railway station, Enfield.
“We sent a number of resources to the scene: one ambulance crew, an emergency planning officer, a clinical team manager, two incident response officers, medics in cars, and our hazardous area response team.
“Two people were assessed at the scene for minor injuries, but they were not taken to hospital.”
