How do I develop the correct natural jog for working western rail?

Developing the correct natural jog for working western rail is fundamentally about preserving and building on the movement the horse was born with rather than refining it toward a specific show ring standard. The natural jog the class rewards is not a performance — it is the horse's genuine working trot expressed through a well-conditioned, supple, forward-moving body with a rider who supports rather than contains it. Developing that expression requires training choices that consistently reward forward energy and natural rhythm rather than managing them. The most direct path to developing the correct working western rail jog is regular riding at the horse's natural working trot in environments where that pace feels appropriate. A trail ride, open field work, or any riding context outside the arena where the horse naturally finds and sustains a forward, rhythmic trot develops the movement habit and the physical strength that the working western rail jog requires. A horse that is regularly ridden at its natural working trot retains and develops that movement. Physical conditioning is an important component of developing the correct jog because a horse that lacks the topline strength and hindquarter development to sustain forward, rhythmic movement comfortably will lose quality as the class progresses even if it begins the class in the correct frame and energy. Hill work at the trot, pole and cavaletti work at a working trot, and any exercise that builds the carrying and pushing power of the hindquarters develops the physical capacity that sustained correct jog movement requires. Within the training program, rewarding the natural forward jog consistently — releasing a light leg aid when the horse finds the correct rhythm, and adding light leg when the horse falls below it — builds the self-regulation that competitive working western rail requires. A horse that regulates its own jog pace without constant rider management in training will regulate it in competition as well.
