Snowboarding holiday, on a train, from the U. K. to the alps, called the snowball?

I remember maybe a year ago seeing " The Holiday programme" on BBC 1. They were featuring a snowboarding holiday where you get on the train in the U K and it goes all the way to the alps somewhere. It had a Disco on it and everyone was partying. I think it was called The Snowball. Can anyone tell me more about it? And if it's still running?

Answers:
You want to book the snow train to Moutiers. We did it to get to meribel. Crazy way to start your boarding holiday, and gets you there a day before your fellow flying boarders ( a day that you will need to recover from your crazee hangover).
