One of the most notable new additions to the Call of Duty: Warzone map recently was the freight train, which came to the game in Season 5. Players and teams can climb aboard the train to find loot, and the train has proven to be a popular place for skirmishes.

Getting the train into the game was Infinity Ward's first step in building out additional features for it. In the future, developer Infinity Ward is looking to add more possibilities focused around the train.

"We have lots of ideas around [the train]," multiplayer director Joe Cecot told Red Bull. "We wanted to get it in there in Season Five and have it be a fun thing to interact with, where you have a lot of movie moments of vehicles chasing trains, people fighting over the train, [that sort of thing]."
