In 2010, KLW developed and began manufacturing EPA-certified and CARB-verified Tier 4 near-zero-emissions locomotives that were sold throughout the country.   Responding to environmental carbon-reduction goals announced by Class 1 railroads, in late 2024 KLW developed and began producing Belle, a patented 3200 hp-equivalent battery-powered locomotive with an onboard 700 hp charging genset that eliminates the need to recharge the battery using shore power. The self-sustained, scalable hybrid solution does not require DEF and will accommodate shore-power charging when available. Belle produces 50% or greater fuel savings in a variety of applications including hump service, local service, and flat switching.   While continuing to produce its traditional near-zero-emission products, KLW has expanded its battery offerings to now include wayside batteries and starting batteries and will offer additional battery products for the rail market in the coming months.   # What We Build ### Battery Electric Locomotives - ### 50% or greater fuel savings in all applications - ### 24/7 Availability, shore power never required but optional - ### Available with AC or DC traction on all platforms - ### 10+ year life expectancy [Technical Report](https://www.goklw.com/hubfs/Belle%20fuel%20and%20emission%20analysis%20v2.pdf?hsLang=en) [Learn More](https://www.goklw.com#lead) - ### Regenerative braking - ### TMV control system - ### Lithium iron phosphate batteries offer thermal stability - ### Operational between -40°F and 140°F - ### No infrastructure costs ## Battery Products ![Starting Battery](https://www.goklw.com/hs-fs/hubfs/72%20V%20Hero%201.png?width=1280&height=716&name=72%20V%20Hero%201.png) - ✓Starting batteries for rail applications ![Wayside Battery](https://www.goklw.com/hubfs/waysidebattery2.png) - ✓Wayside batteries for rail applications [Learn More](https://www.goklw.com#lead) ## Near Zero Emission Locomotives KLW builds low and high horsepower locomotives that are both EPA Tier 4 Certified and CARB Verified. ![cummins-3 (1) (1)](https://www.goklw.com/hs-fs/hubfs/cummins-3%20(1)%20(1).jpg?width=200&height=133&name=cummins-3%20(1)%20(1).jpg) #### Above 4K HP High horsepower for heavy duty line-haul applications.
