The Samaritans are launching a new campaign to encourage more open discussion of mental health issues.
The focus of "The Big Listen" is on train stations across the country today.
It is to highlight how sparking a conversation with someone and listening to their concerns can help save a life.
Cindy O'Shea, regional director for Samaritans Ireland, explains what the aim is.
"It's really just to try and let people know that we're there, we're available to listen [to] whatever is going on for them in their lives," she said.
