Is there a service for finding railway tickets with the ability to select the top / bottom seat?

Question

Computer networks

I need to find a suitable train ticket. Interested only in the lower places. On the Russian Railways website, to find out if there are suitable lower seats, you need to enter each train, and to find out the price for a seat, you still need to fill out passport data every time. Is there a service where you can choose the direction, date, reserved seat / compartment, lower / upper and get available seats with prices for them?

Answer 1

There are services that sell tickets more expensive but show which seats are free on flights. Google without problems

Answer 2

"There are services that sell tickets more expensive but show which seats are free on flights. They google without problems," why? looked at the previous link www.flydex.ru/aviability/Sankt-Peterburg/vse_reisy for seats, everything shows both the number of seats and the price, and it is unchanged until the final design

Answer 3

Hah, the question is still relevant today) From my own experience, I look at train tickets at https://rzd.tickets.ru/ and it's really convenient. As for air tickets, I look at the same services, but I buy on the websites of airlines.
