HUDDERSFIELD railway station now has life-saving equipment in case anyone collapses with heart problems.
The busy station has two defibrillators and nine staff who are trained how to use them.
This means someone will be on hand at the station around the clock if there is an emergency.
The Government's Health Department has a national scheme providing defibrillators at busy places, such as railway stations and airports.
West Yorkshire Ambulance Service is responsible for the defibrillators at Huddersfield railway station, along with those at Leeds Bradford Airport and Leeds and Wakefield Westgate railway stations.
The service's community defibrillation officer, Lee Gray, said: "There are 110 static sites across England, not just at railway stations but in shopping centres, airports and bus stations.
"By placing defibrillators in the community we are giving more people who suffer a cardiac arrest in a public place a better chance of survival."
Angela Hunte, deputy manager at Huddersfield railway station, said: "We take on the training on a voluntary basis.
"Thankfully, so far we haven't had to use our skills.
"But with thousands of rail users passing through Huddersfield station daily I'm sure they will be needed one day.
"Besides, if someone were ever to collapse - whether they're a passenger or a colleague - at least I know how to help them.
"I can't think of anything worse than standing by and watching someone suffer," she added.
The ambulance service will make sure Angela and her colleagues keep their skills and knowledge up to date.
They have already completed the group's first refresher training course.
Emergency medical technician and trainer Neil Kirk said: "It's important the volunteers don't forget what they have learned and that should their skills ever be called upon they can safely and confidently use them.
"Every 180 days we'll provide refresher training in basic life support, airway management, scene assessment, cardiopulmonary resuscitation and defibrillation," he added.
