Can I vape on a train?

Unfortunately when it comes to public transport, this is a sector where vaping is almost entirely forbidden in Ireland. Iarnród Eireann, Dublin Bus and Bus Eireann have banned vaping completely from their vehicles, as have Aer Lingus and Ryanair.

Iarnród Éireann treats vaping in an identical manner to traditional cigarettes and they cannot be used on board trains, within offices or in enclosed station areas.
