Sleeping train from Zurich to Florence?

I am currently located at Zurich, Switzerland and would like to get to Florence over the next three days. Someone mentioned there are sleeping there, which I like the sound of as they as probably quicker than the day time ones. Does anyone have any details of these? As you can see it is urgent so your prompt answers would be well received.

All you need to do is to go to this link - http://www.eurorailways.com/products/night_trains/zurich_to_florence.htm. There, you can book the train, see how much it costs, reserve dinner if you would want it, and so on. While I have never travelled by sleeper train on this route, I have done so across Italy and have always had good experiences, though I know that often you have to book the tickets in advance. Get on to it, I'd say.
