Rail passengers and staff received free CPR lessons at Aberdeen Station on Monday.
The demonstrations took place as part of European Restart a Heart Day.
It comes as figures show the number of people being successfully resuscitated following a cardiac arrest in Scotland has risen.
Volunteers working with the charity Save a Life for Scotland taught heart-starting skills to staff, passengers and station visitors.
ScotRail Alliance's director of safety and sustainability David Lister said: "We place huge importance on keeping our customers safe and well, and anything we can do to make sure everyone's prepared if there's an emergency on our trains or in a station is vital.
"I encourage as many staff and customers as possible to learn the skills of CPR.
"Sadly, we never know when we may need them and they may help save a life."
The day of action is part of the charity's aim that by 2020 there will be 500,000 people in Scotland trained to administer CPR in the event of someone having a heart attack.
Every year, more than 3000 people were treated for an out-of-hospital cardiac arrest by ambulance crews.
