ACS Railroad Solutions LLC is a U.S.-based railway technology company providing locomotive systems, diagnostic equipment, connectivity products and aftermarket solutions for railroad operators. Based in Dunwoody, Georgia, the company has supplied Class I railroads with cabling and communications equipment used in the implementation and continued development of Positive Train Control (PTC). Its current portfolio is focused on improving locomotive availability, maintenance efficiency, operational safety, connectivity and energy performance across modern rail operations.
The company’s product range includes railyard diagnostic devices, railway sensors, locomotive connectivity equipment and technologies designed to modernize existing locomotive fleets. Solutions include PTC connectivity kits, locomotive antennas, Ethernet and wiring systems, speed and temperature sensors, multi-unit test equipment and maintenance diagnostic tools. ACS also develops locomotive enhancements that automate or improve existing systems, helping maintenance and operations teams reduce troubleshooting time, support regulatory compliance and obtain more reliable operational data.
Energy efficiency is another major area of ACS Railroad Solutions’ portfolio. Its TwinPulse Locomotive Energy System uses a 55 kWh lithium iron phosphate energy module to reduce locomotive idling while maintaining power for onboard systems and supporting reliable engine restarts. Remote data tools can measure fuel savings and greenhouse-gas reductions, connecting locomotive energy management with broader sustainability objectives. Through its combination of railway electronics, sensing, maintenance technologies and energy systems, ACS supports railroad operators seeking to modernize existing fleets without relying solely on complete vehicle replacement.
