What Higher Power Industries does

Higher Power Industries (HPI), founded in 2013 by Warren J. Azzara, Jr., is a privately held rail services and power generation company headquartered at 940 Nepperhan Avenue in Yonkers, New York. HPI operates two divisions: a Rail Division that delivers AAR-1003 certified locomotive overhaul, upgrade, repower, and renewal parts services for commuter authorities, Class 1 railroads, regional railways, leasing companies, and OEMs across EMD, GE, and Alco platforms; and a Power Generation Division that supplies standby and prime power generator sets, transfer switches, load banks, and consulting for commercial customers. Named customers include NCDOT (overhaul of seven EMD F-59PH locomotives), Nashville RTA Music City Star (overhaul of four EMD F40PH-2 units), and Caltrain (fifteen 425 kW CAT C15 HEP systems).

Core technology centers on locomotive mechanical and electrical modernization, including Head End Power (HEP) systems integration with cooling, charge air cooling, exhaust, mounting, and HEP controls; EPA Tier 0+ emissions solutions via Mechanical Unit Injection (MUI) to Electronic Fuel Injection (EFI) conversion and diesel-to-CNG/LNG dual-fuel conversion; microprocessor retrofits such as EM2000 logic boards and Siemens Traction Control components; and friction-to-roller bearing traction motor conversions for extended maintenance intervals. HPI maintains technology partnerships with Caterpillar, Cummins, MTU, GE Transportation, and EMD to support multi-platform service coverage.

HPI's business model combines project-based professional services (locomotive overhaul, modernization, consulting, and project management), hardware sales (new and rebuilt locomotives, renewal parts via RFQ), and managed services (contract maintenance). Pricing is quote-based, varying with locomotive condition and work scope. Revenue is not publicly disclosed. Distribution is exclusively direct enterprise field sales targeting government commuter authorities and railroad operators, with on-site installation, training, and commissioning capability delivered globally across North America, South America, Australia, and the Middle East. The company holds AAR-1003 certification and Transit Vehicle Manufacturer designation from USDOT.

Expansion highlights5 records

Others

• Cummins: Cummins is a core OEM engine supplier for HPI's Head End Power and locomotive repower offerings. It is a strategic technology partner for engine selection and aftermarket support, and a related comparator given HPI's HPI-led engine rebuild and fuel conversion work on Cummins-powered locomotives.
• Caterpillar (CAT): Caterpillar is both the parent of Progress Rail/EMD (HPI's primary competitor) and a key OEM supplier of CAT C15 engines that HPI integrates into HEP systems. This dual supplier/competitor relationship is central to HPI's positioning.

Broad incumbents

• Alstom: Alstom is a global rail rolling stock and services OEM with a large installed base in North American commuter rail (including HPI executive Gary Walsh's prior role at Alstom Train Life Services). HPI's commuter overhaul work for agencies like NCDOT and Nashville RTA competes with Alstom's aftermarket service portfolio.
• Wabtec Corporation: Wabtec (formed from Westinghouse Air Brake and GE Transportation) is a global rail equipment and services giant with extensive locomotive modernization, components, and digital rail capabilities. HPI's GE-platform locomotive work (DASH 7/8/9, AC traction) overlaps directly with Wabtec's installed-base service business.
• Progress Rail (Caterpillar / EMD): Progress Rail, a Caterpillar subsidiary and owner of EMD, is the OEM-affiliated market leader in locomotive manufacturing, remanufacturing, and aftermarket services. HPI's EMD-specific overhaul, repower, and engine rebuild work (547, 645, 710) directly competes with Progress Rail's EMD service network.
• Siemens Mobility: Siemens Mobility supplies locomotives, components, and rail services globally. HPI's traction control and locomotive electrical work intersects with Siemens' installed base, and Siemens is both a potential competitor (for modernization) and a component supplier relationship for HPI's HEP and control systems.

Direct peers

• National Railway Equipment (NRE): NRE is a long-established US locomotive remanufacturer and parts supplier serving Class 1, commuter, and international freight operators. It is the most direct functional peer to HPI's locomotive overhaul, repower, and renewal parts business.
• MotivePower Industries (Wabtec): MotivePower, a Wabtec subsidiary, specializes in locomotive manufacturing, remanufacturing, and switcher production. It is a direct peer in the locomotive rebuild and repower segment that HPI addresses, particularly for commuter and freight customers.

Regional players

• Downer EDI (Downer Rail): Downer EDI is a major Australasian rail services and rolling stock provider, and overlaps with HPI's Australasian market (Australia/New Zealand) where HPI's Jim Griffiths is developing accounts. Downer is a regional peer in locomotive maintenance and modernization outside North America.

Emerging players

• Brookville Equipment Corporation: Brookville manufactures and remanufactures locomotives and mining equipment, including new and rebuilt switchers and freight units. It overlaps with HPI's locomotive modernization work for niche freight, mining, and industrial customers.
