A pneumatically piloted retainer valve for bottling brake cylinder pressure that can be set and released in response to changes in the brake pipe pressure. Pneumatically piloted retainer valve provides a brake cylinder 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 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 provides for piloting of the retainer valve in response to a predetermined reduction or threshold increase in brake pipe pressure.
