A holiday steam train carrying around 50 passengers has derailed after crashing into a tractor on an unmanned level crossing.

Several people were injured when the miniature locomotive collided with the stationary vehicle on the Romney, Hythe and Dymchurch Railway.

One witness said she saw the driver "leap from the train" and take passengers to safety after one of the carriages collapsed on its side.

Paramedics treated five people - including the driver - at the scene for minor injuries as fire crews worked to secure the locomotive's boiler, which was feared to be at risk of exploding. The other passengers were checked over as a precaution.
