How Many Miles And Hours Travel Is It From Surrey, England To Venice, Italy By Train?

Where in Surrey are you?  North near London, or further South?

And how do you like to travel, leisurely or bombing along, sleeping in a sardine can?

There are luxury train journeys from London to Venice, that typically travel for 29 hours non-stop. That won't include any security controls before you get onto the train in London, and won't include whatever time it takes for you to get from Where-ever in Surrey to Victoria station.  Costs over £1000 for the luxury return.

It's a bit faster (and a darn sight cheaper) if you take the Eurostar, from Waterloo station (London) to Paris, change trains in Paris for the overnight express service to Venice.  That journey can take just a bit under 20 hours, costing not much over £200 (depending on season, and how tightly packed you like your sleeping berth).

Distance wise, it's nearly 1000 miles of train travel London to Venice.
