Transportation Technology, Inc. is the leader in the design, development, manufacture, and supply of diesel power systems for the Commuter Railroad industry throughout North America.  Specializing in the locomotive Head End Power (HEP) systems, we have a thorough understanding of the application, including equipment selection, maintenance, and service of these critical systems.

As an original equipment manufacturer (OEM) for the major engine manufacturers, we have the ability to work directly with their engineering departments to determine the proper engine for each specific application. Further, with the enactment of the new more stringent EPA regulations governing these systems, our goal is to provide the most environmentally friendly package available, while taking into account the unique design parameters necessary for the harsh environment of a passenger locomotive.
