The SpillX Locomotive Fueling System

SpillX is a new high flow pollution prevention locomotive fueling system developed by MPL Technology to bring aviation fueling technology to the railroad industry. The system has been designed to reach fueling rates up to 600 gallons per minute using a dry break connection which ensures no fuel leakage at disconnect.


The system was developed using proven aircraft fueling technology and modifying the components to meet the needs of the railroad industry.  The result is a robust durable system that provides an enhanced level of safety as well as significantly increased fueling rates.

The SpillX system was designed partially around the intended goals set forth in the 2000 AAR locomotive fueling recommended practice (RP-5503).  These goals include providing higher flow capabilities over traditional locomotive fueling systems, reducing leakage by utilizing widely available dry-break connections, and implementing a reliable automatic overfill protection mechanism.  However, the SpillX system is also different from the guidelines set forth in that recommended practice.  It requires no special electronic sensors to be installed on the locomotive, nor any special controller on the fueling platform.  The installation of the system is simple and can be completed track-side in a matter of minutes with little to no modifications to the existing locomotive fuel tanks.
