How do you ride effectively in a large working western rail class with many horses on the rail?

A large working western rail class — twenty or more horses traveling the same direction — presents specific management challenges that experienced competitors prepare for, and handling these challenges well is itself part of the impression the judge evaluates. Positioning relative to other horses is the primary challenge. A horse that is crowded, that must constantly adjust its pace to avoid running up on another horse, or that is being run over from behind will not show its best movement. Experienced competitors develop awareness of the entire class picture — knowing where the fast movers and the slow movers are and positioning to give their horse a clear stretch of rail rather than being caught in traffic. When the rail is crowded, moving to the second track — one horse width off the rail — is always permitted and gives the horse more room. Judges do not penalize a horse for not being directly on the rail, but they do see a horse that is fighting for space or being blocked by other horses. Taking the second track voluntarily is better horsemanship than staying pinned on the rail in traffic. Passing and being passed by other horses is a management test for the horse. A horse that speeds up when passed, or that slows when another horse moves ahead, is not confirmed in its pace. Training specifically for this by having other horses pass during schooling sessions, and correcting any pace change immediately, prepares the horse for the class environment. During the class itself, the rider's job is to make the horse look effortless. Avoiding visible corrections — releasing the rein to reposition it, applying visible leg aids, adjusting the horse's frame — is important because every visible correction tells the judge the horse is not confirmed. Making whatever management is necessary as invisible as possible is part of riding competitively in a rail class.
