Abstract
Systems, apparatus, and methods are disclosed that include an internal combustion engine having a lubrication system with an upper storage reservoir for receiving lubrication fluid from the internal combustion engine. The upper storage reservoir maintains a supply of lubrication fluid to a lower storage reservoir even while the internal combustion engine is inclined due to operation along severe grades. The lower storage reservoir supplies fluid for circulation to the internal combustion engine.
