Iron Horse puts the player in the role of a cowboy tasked with stopping train robbers. The player moves sideways along the train, either inside or on the roof, and can choose from three weapons: fists, a whip, or a pistol. Additionally, a special weapon is available that creates a fire blanket, defeating all ground enemies. Along the journey, enemy cowboys appear, attacking with weapons like pistols, whips, fire, or dynamite. Each hit costs a life. Gold sacks scattered across the train can be collected for extra points. At certain points, progress is blocked by larger groups of enemies that must be defeated to continue and eventually claim a large pile of gold. Skill and quick reactions are essential to complete the mission.
