The NS 7400 was a 0-6-0 tank locomotive operated by Nederlandse Spoorwegen, primarily designed for shunting and light freight duties. With six coupled driving wheels and no leading or trailing axles, it provided strong low-speed traction and excellent control in yards and industrial areas. The 7400 class was valued for its simplicity, durability, and reliable performance in day-to-day switching operations.
