Passengers had to be evacuated from a train after some saw smoke "billowing through the carriages".
Passengers travelling from Plymouth to Truro complained of a "burning smell" on the train, which was forced to stop in Liskeard at 10:15 GMT on Monday.
The evacuated passengers were then made to wait on the station's platform before taxis were laid on for them.
Cornwall Fire Service said a small fire in the engine compartment was extinguished.
Passenger Andy Smith, from Plymouth, said: "I could smell an electrical burning smell. Then a couple of passengers came from further up the train and smoke was following them.
"I spoke to a couple of the First Great Western employees, and they waited about 30 minutes and we got taxis on from there."
