Quick thinking passengers administered first aid after a train driver suffered what is understood to be a heart attack while on duty in the Scarborough area.
The emergency was at the Rillington Crossing at Sherburn, in Ryedale, and the driver managed to bring his train to a safe stop after becoming ill.
A First TransPennine Express spokesman said the affected service ran from Scarborough to Liverpool Lime Street and added: “A member of traincrew was found to be seriously unwell and emergency services were called and responded. Assistance was also provided by medically trained passengers on board the train.
“A member of FTPE staff was later airlifted to Castle Hill hospital in Hull where he remains under treatment.
“The service was taken to Malton where it was terminated. Passengers were transferred to another service for their onward journeys.
“I would like to take this opportunity to thank those passengers who assisted for their help and support in this matter.”
Ambulance and fire services were called to the scene yesterday at about 10am.
