A brake cylinder maintaining system includes a main valve comprising a first diaphragm, a second diaphragm, and a valve member, with the first diaphragm having a reference pressure on one side of the first diaphragm and a brake cylinder pressure on an opposite side of the first diaphragm. The second diaphragm having a brake cylinder pressure on one side of the second diaphragm with the first diaphragm configured to move between a first position and a second position based on a differential between the reference pressure and the brake cylinder pressure. The valve member is configured to place a brake cylinder in fluid communication with a brake pipe when the first and second diaphragm are each in the second position and configured to isolate a brake cylinder from a brake pipe when the first diaphragm or the second diaphragm are in the first position.
