Engine Room Meaning in Rugby Union

The engine room is a popular nickname for the two locks who play in the middle of a scrum. These players wear the numbers four and five and are usually the tallest athletes on the entire team. They are called the engine room because they provide the primary power for pushing the scrum forward. Without their massive leg strength and weight, the front row would have no support during the physical contest. These players are also responsible for jumping in the lineout to catch the ball high in the air. Their work is often less visible than the fast backs, but it is essential for winning the game. They do the heavy lifting and grueling work that allows the rest of the team to shine. For example, the two locks will bind tightly together and drive their legs to shove the opposition backward. This immense effort wins a penalty for their team by forcing the other side to crumble. It is about raw power.
