A QUICK-THINKING railway guard’s time in his old job on a hospital cardio ward came in handy when a commuter had a heart attack on the platform.

Jack Miller, of Oban Road, Southend, won the admiration of his wife and workmates, after rushing to the aid of a 48-year-old man who collapsed at London’s Limehouse station in the rush hour.

Jack, 24, a former healthcare assistant at Southend Hospital, immediately started CPR while he waited for a paramedics to arrive.

He said: “I was doing some overtime and a passenger came down and said someone had collapsed.

“We got up on the platform and everyone was surrounding the chap. I noticed he had stopped breathing and was going into arrest, so I quickly rolled him over and showed a passenger how to do chest compressions whileI opened his airway.”

Commuters crowded the platform at the busy station while other c2c staff helped manage the crowds. When a paramedic arrived, Jack worked with him to get the man breathing again, then helped carry the man to a waiting ambulance.

Father-of-two Jack added: “It wasn’t really until I got off the train at home that it sunk in.”

Proud wife Siobhan Miller, 25, said: “I think he needs to be praised for it.

"He was the only member of staff working who knew CPR.”

Jack’s boss, c2c driver manager Brett Cooper, was quick to do just that, hailing Jack’s actions as “outstanding”.

He said: “Since Jack joined us in October 2011, he’s always been willing to go that extra mile for our customers.

“With his experience working in a hospital cardio ward and his calmness under pressure, he was the ideal person to be on the scene. Everyone at c2c is very proud of him, and I know his family is, too.”

A London Ambulance Service spokesman said: “The man was in cardiac arrest. Extensive efforts were made to resuscitate him on scene and the way to the London Chest Hospital, in Bethnal Green.”

The spokesman added the man was breathing when he reached the specialist cardiac unit at the hospital, but was unable to give details of his condition, or confirm if he had survived.
