Reduce locomotive operating cost & emissions
ThermaDynamics Rail LLC (TDR) was founded in 2010 by Claudio Filippone, Ph.D. to develop waste heat recovery and conversion technologies for rail applications.
TDR core team is formed by highly skilled engineers from various disciplines, supported by in-house CNC machinists, welders and technicians fully dedicated to transform complex engineering projects into affordable, safe and reliable products. TDR core team is trained to drive TDR high-power turbo-jet heat source forming a test-rig that enables reliability and endurance testing of ThermaRail products as well as products developed for non-rail applications. In this manner, TDR-designed and manufactured components, as well as operational power conversion enclosures, are tested at power rating equivalent to locomotive maximum power (notch 8 setting) prior to installation on locomotive.
TDR operates through three distinct facilities in northern Virginia, dedicated to high-precision manufacturing, assembly and high-power testing.
TDR team is proud of applying cutting edge aerospace technologies and modern electronic power and control systems to relatively old and new locomotive designs to improve their efficiency, lower pollutant emissions and decrease their operating cost.
Across all of TDR activities, TDR team is committed to maximize efficiency, capture and convert waste thermal energy into useful pollution-free electricity.
