A pneumatically piloted retainer valve (10) for bottling brake cylinder pressure that can be set and released in response to changes in the brake pipe pressure. Pneumatically piloted retainer valve (26) provides a brake cylinder (BC) pressure retaining function that bottles applied brake cylinder pressure in the brake cylinder when brake pipe pressure is less than a predetermined cut-in pressure. Pneumatically piloted retainer valve includes a retainer valve (10) movable between a reset position, where brake cylinder pressure is in communication with exhaust and a bottle position, wherein brake cylinder pressure is isolated from exhaust. A retainer pilot control valve (40) provides for piloting of the retainer valve in response to a predetermined reduction or threshold increase in brake pipe pressure.
