Abstract
Systems and methods for accumulating air in an auxiliary reservoir of a railroad car are disclosed. In some embodiments, the method may include charging an air brake system. Air pressure in the air brake system may reach a predetermined value. Once this predetermined value is reached, additional or excess air may be bled from the air brake system and the additional or excess air may accumulate in an auxiliary reservoir. The auxiliary reservoir may be adapted to supply air to an auxiliary cylinder or other types of pneumatic components or equipment.
