What does целое купе mean while booking on rw.by?

Hello.

I plan to travel to Russia in end-Sept 2026.

I was making my train booking from Vladivostok to Irkutsk on www.rw.by It gave me an option of “целое купе” in SV (1st class). What does this mean? Do I have to pay for 2 tickets to book the complete kupe?

Can someone who has done this and familiar with the booking process please help me understand this.

Thank you in advance.

Regards.

I think it means whole compartment and yes you would pay more. Not sure if its actually full 2x pricing though.

I agree - it means the “entire compartment” however if there are 4 beds, you would not necessarily pay 4 X the fee. Here is an excerpt that I found on a website:

Many people mistakenly believe that you will have to pay four times more for such comfort. This is not entirely true. Russian Railways provides a discount when purchasing all seats in the compartment. Its size may vary, but the logic of the carrier is clear: servicing one passenger (fresh linen, cleaning) requires fewer resources than four. As a result, the total amount will be less than just multiplied the cost of one ticket by four, but, naturally, significantly higher than the price for one seat. This is a price to pay for privacy and space.
