OCS & Traction Power

Providing knowledge and expertise to support North America’s growing public transit systems.
OCS & Traction Power

For more than 30 years, L.K. Comstock has played an integral role building, deploying and maintaining traction power systems across the U.S. Our project portfolio includes some of the most trafficked transit systems in the world, including Seattle’s Sound Transit, Dallas’ DART, MUNI in San Francisco, New York’s Metro North Railroad and southern California’s MetroLink. We’re trusted for our commitment to quality, our in-depth knowledge of traction power systems and our ability to work cooperatively with transit authorities.

We have more than 30 years of traction power experience under our belts, which means we’re ready to take on any range of projects in the sector. Our technical expertise, regulatory knowledge and skill working as both prime contractor and as a subcontractor make us the top choice of transit authorities across North America.


Trust us for:


  • Installing AC and DC overhead catenary systems, third-rail systems and automated people mover power systems
  • Revitalizing existing infrastructure
  • Installing systems on new lines and extensions


Our teams work closely with engineers, managers and relevant transit authorities to create a fully integrated work plan that outlines the entire project process and eases the shift from system design to field operations. As work commences, L.K. Comstock secures the necessary resources and coordinates labor to ensure a smooth process every step of the way. Our goal is to make RailWorks the strategic, knowledgeable partner every transit project deserves.

From contractor to passenger, everyone on our rail is important to us. That’s why, when it comes to safety, we’re all-in every time.


If we’ve learned anything in our many years, it’s that you can never be too informed. RailWorks and L.K. Comstock are wellsprings of industry knowledge, leveraging decades of experience to make critical decisions and help a project meet its deadlines and stay within budget.


Every city is different and every transit authority has different priorities, whether it’s NYC or DC. Here at RailWorks, we know this well, and consider our team’s ability to adapt to the particular needs of a worksite one of our greatest strengths. It means we’re always doing the best work we can, and that’s good for everyone.
