When you reach the station, you must first go through airport-style security controls into the departure area.

For soft sleeper travel, you must then find the appropriate waiting lounge for your train. There are a number of different waiting lounges, and the electronic message boards show which is the right one for each specific train. Tickets are checked on entering the lounge, so you can be sure you are in the right place.

Inside the lounge, the electronic message boards show the trains departing from that lounge, for the next 24 hours. Trains are usually allocated between lounges so there is 0.5 hour or more between each departure from that lounge.
