About the Company

Rail Propulsion Systems is a California based Technology Company dedicated to modernizing transportation and eliminating congestion in our cities and transportation corridors. Our technologies are tailored to existing locomotive platforms providing commuter rail agencies and short line railroads with low cost opportunities to improve the operations of their fleets. Our solutions integrate proven after treatment, alternative fuel and hybrid energy storage system technologies in a manner that is both low risk to the operators and disruptive to current reliance on diesel.

With our partnering companies, we improve existing locomotives through increases in efficiency, performance and reliability while reducing emissions and operating costs.
