Definition
A "yardmaster" is a person in charge of a railroad yard, coordinating train movements and ensuring the efficient operation of the yard. The yardmaster oversees the switching and classification of railcars, organizing them into trains for different destinations. They are responsible for the safety and security of the yard. It is a critical role in railway logistics. Think of them as the air traffic controller of the railroad. Unlike a train conductor, they don't travel with the train.
