Abstract: A brake cylinder maintaining system produces a brake cylinder reference pressure based on the difference between the brake pipe pressure and the auxiliary reservoir pressure and then feeds that pressure to a choke and a volume so that the ratio of the reference area of the choke to the volume of stored brake cylinder reference pressure is substantively equal to the ratio of a brake cylinder charging valve area to the brake cylinder volume. The resulting reference pressure may be used to adjust brake cylinder pressure by providing the reference pressure to a standard quick service limiting valve or to a relay that can selectively charge or exhaust the brake cylinder.
