Special train "Lev Tolstoy" (Leo Tolstoy)
The overnight train "Leo Tolstoy" (№ 31/32) goes daily from Moscow to Helsinki from the Leningradsky station.
A ticket to the first-class car is much more expensive than a ticket for the second-class or the third-class car. But for this money, besides the air conditioner, you will get a personal bathroom with heated floor and shower, a LCD TV, a DVD-player, an additional upper sleeping shelf of 80 cm wide and a comfortable sofa, which is laid out in a half-spaced bed with a width 110 cm.
At the end of the first-class car there is a lounge bar. You can buy drinks from the conductor, as well as order dishes from the restaurant car.
By the way, another advantage of the "Lev Tolstoy" train for international trips is that you can exchange money directly on the train, and on the way back you can also get a refund on Tax Free checks.
