On the show today Ray spoke to Lieutenant Alex Janson who visited Ireland during the Summer.
On Thursday July 11th he left his camera bag with his camera, money and passports in it, on the DART.
He chased after the train but it was too late.
But much to his surprise, three teenage girls handed the bag in with all its contents. Now he wants to track down the girls and thank them in person.
His brilliant blog post about it can be found here:
Here's his chat with Ray:
If you are those girls or know who they are, get in touch to [email protected]
Here are some of the lovely images Alex now has thanks to the three girls:
