Penn Machine Company

What Penn Machine Company does

Penn Machine Company, LLC is a specialty industrial manufacturer founded in 1920 (originally as Penn Smokeless Coal Co.) that produces wheels, wheelsets, axles, gears, and gearboxes for OEM and aftermarket applications. Headquartered in Johnstown, PA with a secondary manufacturing and engineering site in Blairsville, PA, the company serves five core verticals: mass/urban transit, locomotive/heavy rail, industrial and mining, oil and gas, and power generation (air preheater gearboxes). Its subsidiary Penn Locomotive Gear (PLG) supplies traction gears, pinions, and motor armature shafts to freight and commuter rail customers worldwide. Notable technical capabilities include in-house heat treatment and a proprietary Cubic Boron Nitride (CBN) grinding procedure for restoring traction gear tooth profiles with minimal stock removal, plus authorized-source status for Ljungström Air Preheater gearboxes under ARVOS Inc.

The company operates a direct enterprise field-sales model via four regional representatives covering Eastern US, Western US/Alaska, Canada, and General Sales & International. Revenue is generated through three streams: OEM hardware sales (wheels, wheelsets, axles, gears, gearboxes), aftermarket parts and service, and rebuild/repair services (gearbox rebuilding, gear re-profiling, wheel re-machining, rubber block replacement). Pricing is quote-based and not publicly disclosed. Distribution reaches end customers including transit authorities, railroad companies, industrial and mining operators, and power generation facilities, with no public list pricing and sales cycles consistent with long-cycle, specification-driven industrial procurement.

Penn Machine holds ISO 9001:2015 certification for both its Locomotive and Transit divisions, AAR M-1003 Quality Assurance Program Approval through MxV Rail, and AAR PMBP, PMCB, and PMJP certifications. It is a member of the American Public Transportation Association (APTA) and the American Gear Manufacturers Association (AGMA). The company is a wholly-owned subsidiary of The Marmon Group, itself owned by Berkshire Hathaway Corp., with 101-250 employees as of the latest available data.

Core offering

Penn Machine Company manufactures wheels, wheelsets, axles, gears, and gearboxes for OEM and aftermarket use in mass transit, freight rail, industrial, mining, marine, and power generation applications. The company also rebuilds and repairs transit gearboxes and wheelsets, offering authorized replacement gearboxes for Ljungström Air Preheaters and serving as a major supplier of LORD rubber components for the rail transit market.

Product overview

Penn Machine Company manufactures a comprehensive portfolio of rail transit, locomotive, and industrial components. The core offerings center on wheels (resilient and solid), wheel sets, axles, gears (including Super Gear, pinions, and locomotive starter gears), and gearboxes (transit rail and air preheater). These products are offered as both OEM components and aftermarket replacement parts. The company provides related services including gearbox rebuilding and repair, gear re-profiling, and technical support tools. The product architecture is a unified portfolio of complementary mechanical components and related services rather than a modular software platform, with products serving the mass/urban transit, locomotive/heavy rail, industrial, mining, marine, and power generation sectors.
