What Railworks does

RailWorks Corporation is a privately held, North American specialty rail contractor that designs, builds, and maintains rail transportation infrastructure for transit authorities, Class I and short-line railroads, and industrial customers across the United States and Canada. The company operates through a family of operating companies — PNR RailWorks (Canadian track services), L.K. Comstock (transit electrical, signals, and communications), NARSTCO (steel railroad ties and turnout sets), and RailWorks Track Systems/Maintenance of Way/Signals & Communications — collectively representing 120+ years of operating history and a workforce of 3,000+ employees supported by 30+ regional offices. Service lines span railroad track construction and rehabilitation, transit rail construction, maintenance-of-way, signals and communications, OCS and traction power, bridges and structures, geometry testing (SolidTrack), and specialty rail applications.

The company generates revenue through project-based construction contracts (ranging from single-digit millions to $260M+ for marquee transit projects) and recurring multi-year maintenance agreements. Customers include MTA, CN, SEPTA, Sound Transit, DART, LA Metro, GO Transit, CSX, BNSF, and industrial operators in ports, petrochemical, mining, agriculture, and pulp & paper. Proprietary technology assets include the SolidTrack geometry testing platform, the Blend 70 rapid-set concrete mixer (first in North America), and the RailWorker hi-rail excavator service. RailWorks is backed by Bernhard Capital Partners, a services and infrastructure-focused private equity firm with over $5 billion in AUM, and is led by CEO Jim Sabin (appointed October 2025).

Recent moves6 records

Expansion highlights6 records

Direct peers

• Mannix (a HiRail Group company): Mannix/HiRail Group is a direct competitor in track construction, maintenance-of-way, and emergency rail services for Class I and short-line railroads in the eastern US. Comparable scale and service mix to RailWorks Track Services and Maintenance of Way divisions.
• Herzog Railroad Services: Herzog is a direct competitor offering track construction, maintenance-of-way, signals & communications, and rail material handling equipment across the US. Highly comparable to RailWorks across the same Class I, short-line, and transit customer base and the same end-to-end service stack.
• Zachry Construction: Zachry is a direct competitor in heavy civil transit and rail construction across the southern US, with comparable revenue scale and a similar track record on light rail extensions and rail civil works.
• Kiewit: Kiewit is a heavy civil construction firm that competes head-to-head with RailWorks on major transit and rail capital projects across the US, including OCS, traction power, and systems work. John Young (President, Track & Transit Construction at RailWorks) previously held senior leadership at Kiewit.
• Stacy and Witbeck: Stacy and Witbeck is a direct competitor in light rail and commuter rail transit construction, having delivered projects for many of the same agencies (DART, Sound Transit, Sacramento RTD) where RailWorks competes for electrification and track work.
• Balfour Beatty Rail: Balfour Beatty's rail division competes for the same large transit agency and Class I capital programs as RailWorks, including track, OCS, signals, and civil structures. Operates as a comparable full-service specialty rail contractor in North America.

Broad incumbents

• Wabtec: Wabtec is the largest North American supplier of rail equipment, components, and signaling systems (including GE Transportation merger assets). Overlaps with RailWorks at the equipment and signaling interface though Wabtec is primarily an OEM rather than a contractor.
• Hitachi Rail: Hitachi Rail is a global signaling and CBTC systems provider that competes with Siemens (RailWorks' Fulton-Liberty partner) on the same major transit authority programs. Adjacent rather than direct given Hitachi is OEM-focused while RailWorks is installer/integrator.
• Granite Construction: Granite Construction is a large publicly traded heavy civil contractor that competes for transit and industrial rail work as part of its broader portfolio of transportation infrastructure. Less rail-specialized than RailWorks but overlaps on freight rail and transit corridor projects.

Regional players

• Colas Rail: Colas Rail is a European-based rail infrastructure contractor with growing North American operations in signaling and electrification. Comparable service line-up (track, OCS, signals) but primarily competing on European and select international projects.
