How long is the train from Moscow to St. Petersburg?

About 4 hours on the Sapsan, Russia's high-speed train — city center to city center, with no airport transfer on either end.

How much does the Sapsan cost?

Roughly $40–70 one way, booked on the official RZD site or through your hotel or a local contact.

Can I book RZD with a foreign card?

No — RZD's official booking site does not accept foreign-issued cards. Book through an intermediary (expect a markup), have a Russian contact or your hotel book it for you, or buy the ticket for cash at the station.

Is the train better than flying between Moscow and St. Petersburg?

For this route, most travelers take the train: about 4 hours downtown-to-downtown beats a flight once you add airport transfers and security on both ends. There's no verified domestic flight price for this route to compare dollar-for-dollar, but on total door-to-door time the Sapsan is the default choice.

The train from Moscow to St. Petersburg (Sapsan), and the booking trap

Verified August 30, 2026. Book this before you land — not the morning of.

Moscow and St. Petersburg are the two stops almost nobody skips, and for getting between them, most travelers reach for the train, not a flight: the Sapsan, Russia's high-speed line, in about 4 hours, city center to city center. The route itself is simple. The booking page is where foreigners get stuck.

The route: about 4 hours, downtown to downtown

The Sapsan runs between Moscow and St. Petersburg in roughly 4 hours. Because both ends land you in the city center rather than an airport well outside town, it eats up less of your actual day than the number alone suggests. One way runs $40–70 — book it on the official RZD site, or have your hotel or a host handle it.

Sapsan, one way: ~4 hours · roughly $40–70 · Moscow ↔ St. Petersburg.

The trap: RZD's site won't take your card

Here's what catches people who did everything else right: RZD's official booking site does not accept foreign-issued cards. You can browse schedules and prices without any trouble — checkout is where it fails, the same wall you'll hit trying to prepay other things in Russia from home.

Three ways around it

Book through an intermediary. Booking services and agencies will purchase RZD tickets on your behalf for a markup — the simplest fix if you're planning ahead from outside Russia.
Use a Russian contact or your hotel. Anyone holding a Russian-issued card can buy the ticket directly on the RZD site at face price, no markup, if you have a host, hotel concierge, or contact willing to do it.
Pay cash at the station. RZD ticket counters and machines take cash once you're actually in Russia — the fallback if you'd rather sort it on the ground than prepay.

What trips people up

Filling out the whole RZD booking flow, card in hand, then watching checkout fail with no obvious explanation on the page itself.
Assuming this route needs booking as far ahead as an international flight. It doesn't — payment method is the blocker here, not availability.
Not knowing cash-at-the-station is an option at all, and writing off the train entirely.

Whichever route you pick, get the ticket sorted before travel day — one less thing to manage while you're adjusting to cash-only life on the ground.
