The Russian Railways have finally created something really special and nice: a virtual tour of "Rossiya" Trans-Siberian train (#1/2), which departs from Moscow and goes all the way to Vladivostok. It's possible to see the views from the window, "talk" to the passengers, take a look at the compartments, the restaurant, toilets, and learn a lot of interesting things. The texts are in Russian, but it's pretty easy to navigate through, just click through from the Day 1 to Day 6 in the interface above.

You can view the virtual tour here.
