Please help Snowy come home

My daughter has lost her beloved little white teddy bear Snowy. We think she left him on the 14:50 Waterford to Dublin train on Sat 15 August. He's a white bear, has some tomato based stains and a brown check ribbon tied in a bow stitched to the front of his neck. She hasn't been sleeping very well since he's been gone, she was awake in the middle of the night last night crying 'snooooo-weeee!' and wouldn't nap today. We'd be eternally grateful to get him back. Thanks for reading.
