ACS Railroad Solutions builds on the success of its award-winning Electrolyte Idle Reduction system with the introduction of the TwinPulseTM Locomotive Energy System

Two 27.6 kWh Lithium-ion Phosphate (LFP) batteries are connected in parallel to provide a unique and advantaged solution to minimize fuel usage & GHG emissions and provide unmatched restart reliability


The Next Generation in Idle Reduction
Provides standard AESS functionality coupled with 55 kWh energy module that keeps key locomotive systems (ex: HVAC) powered without idling the locomotive
- Minimize the motivation for system Override
- Drastically reduce Air Pressure drop as a source of engine restarts
- Lead Acid battery discharge eliminated as a restart cause
Extended locomotive engine shutdown intervals (up to 12 hours) can lead to:
- Up to $100K in fuel savings*
- Up to 30 Tons of GHG emissions avoided*
* Per locomotive/per year
Increase Locomotive Availability by Replacing Lead Acid batteries with Lithium-ion Phosphate Technology
- 3- 4 times greater life expectancy due to the superior chemistry of an LFP system
- Near elimination of flat-line battery service interruption through parallel wiring starting redundancy and StrandSafeTM technology
- Zero Lifetime Maintenance
- Improved safety due to elimination of acid splash and arc flash incidents
- Drop-in Replacement – no need to pay for OEM software revisions


Remote Data Dashboard can validate your improved Idle Reduction efficacy and offer insight in to how to generate greater savings
- Highly visible widget quantifies fuel savings and GHG emission avoidance
- Opportunities for further savings are highlighted by displaying instances where the locomotive either exited Battery Mode or was unable to enter it due to manual intervention
- Compare fuel savings across your fleet and review usage patterns which may reveal why some locomotives perform better than others
- Dig deeper with holistic locomotive data including locomotive usage and location history, control system recorded errors and logs of “working” sessions
