Ten people have been evacuated from a train which caught fire.
Smoke could be seen billowing out of the three-carriage train at the old railway station in Kenilworth, Warwickshire.
The engine at the front of the train set alight, the fire service said. Operator Vivarail said it was a test train and all staff were safe.
National Rail's website said trains would not run between Coventry and Leamington Spa for the rest of the day.
Freelance rail journalist Fraser Pithie, who had gone down to watch the test, said the train was a recently converted London Underground test train, which had been running up and down the lines when it came to a halt at Kenilworth.
"The reason it came to a halt is that that there was a fire in the underside of the train where the equipment is," he said....
