Join us at the RSSI C&S Exhibition at the Louisville Convention Center in Louisville, KY. We can’t wait to showcase all of our new trackside power systems including our now patented Switch Boost 120V Systems, Switch Boost 12V & 24V Systems, Solid Oxide Fuel Cells and Stirling Engine Generators. Visit us at Booth #973 on July 9th and 10th, 2024. 

Switch Boost™ Systems

Our innovative and patented Switch Boost™ Systems utilize one or two Ultracapacitor or Hybrid Ultracapacitor modules to provide enhanced power for 12V, 24V and 120V railway power switch applications.


Fuel Cells provide a reliable source of DC power by converting chemical energy into electricity. We currently offer both Solid Oxide Fuel Cells and Alkaline Fuel Cells from 250W to 5kW+ for critical backup power requirements.

Stirling Engine Generators

Stirling Engines combine high efficiency Free Piston Stirling Engine (FPSE) technology with advanced combustion capabilities to efficiently transform propane and natural gas into electricity from 1.8kW to 5.6kW for critical prime and backup power requirements.

Solar (PV) Power Systems

Solar Power Systems provide a reliable and proven source of DC power by converting sunlight directly into electricity. Since the early 1980’s, we’ve provided thousands of Solar Power Systems all across North America from 100W to 100kW for both off-grid and grid-tie applications.

We’re excited to announce that our Switch Boost™ Family of Ultracapacitor-based railway switch power systems recently won Progressive Railroading’s 2024 Reader’s Choice Award for C&S products!

Available at 120V, 24V and 12V, these innovative and patented systems utilize ultracapacitor and hybrid ultracapacitor technology to provide enhanced power and reliability to railway power switch applications, compared to legacy battery-only systems!

Critical Power Systems

We specialize in advanced power generating technologies and over the last 40+ years have been a leader in deploying these technologies to critical infrastructure markets. We pride ourselves on being product agnostic and letting the application drive customer buying decisions.
