Although it ensures certainty of travel, it does not guarantee a berth. A berth will be allocated to the person who reserves an RAC ticket if passengers who already have a confirmed ticket do not turn up before the train departure or get their confirmed ticket cancelled. A berth is split into 2 seats for 2 RAC ticket holders. If there's any last minute cancellations, or if any quota allocations remain unsold, or if any confirmed ticket holders are given a free upgrade (more later), an RAC ticket holder is given the empty berth, the other RAC ticket holder can then convert the 2 seats into a berth.

Eighteen players have accomplished the feat to date, the most recent being Scooter Gennett on June 6, 2017 against the St. Louis Cardinals. No player has done this more than once in his career and no player has ever hit more than four in a game. Bobby Lowe was the first to hit four home runs in a single game, doing so on May 30, 1894. Fans were reportedly so excited that they threw $160 in silver coins ($4,500 today) onto the field after his fourth home run.
