After Patch boarded the 6.49am train from Kilcock to the Dublin station, the Irish Rail sent out a tweet alerting their 18,000+ followers to the lost pup.
Patch's owner, Deirdre Anglin, was already looking for him and logged onto Facebook and Twitter to alert people of her lost dog, and then less than three hours after it was posted, she saw the Irish Rail tweet and went to go pick up the adventurous pooch from the station.
