a circular railway track that allows trains to change direction without needing to turn around
A balloon loop is a circular or looped track used by trains to change direction without needing to turn around. This type of track layout allows a train to move in a complete circle, letting it continue its journey in the opposite direction without backing up. Balloon loops are commonly found in areas where there is limited space or when trains need to switch directions quickly, such as in train yards or at the end of certain rail lines.
