OCS & Traction Power Providing knowledge and expertise to support North America’s growing public transit systems. For more than 30 years, L.K. Comstock has played an integral role building, deploying and maintaining traction power systems across the U.S.

When the overhead line was raised in the Simplon Tunnel to accommodate taller rolling stock, a rail was used. A rigid overhead rail may also be used in places where tensioning the wires is impractical, for example on moveable bridges. In modern uses, it is very common for underground sections of trams, metros, and mainline railways to use a ...

MAC designs, manufactures and supplies OCS material and equipment for today’s light rail, tram, electric trolley bus, streetcar and commuter rail systems. We offer a complete solution for our customers, whether they be the installer, operator or maintainer of the system.

OCS in Railway commonly refers to Overhead Catenary Systems, which are used to supply electric power to trains through overhead wires, enabling efficient and sustainable transportation. These systems are essential for the operation of electric trains, ensuring a reliable power source along the railway network.

The rigid catenary is an Overhead Contact System (OCS) that can replace, with many advantages, the contact wire with sustentation wire, the third rail or the suspended bimetallic T-rail. It is formed by an aluminium alloy profile, which accommodates the copper contact wire, with a great cross section for the current that allows operative OCS ...

Gannett Fleming assists railway owners to achieve their critical missions through rail systems solutions, including track, traction power, electrification, overhead contact systems (OCS), signaling, and other train control and communications systems, as well as operations simulation and rail systems specialized project and construction management.

The delivery of a more sustainable railway has increased demands for the electrification of rail networks, enhancing the need for monitoring and predictive maintenance methods for thousands of miles of overhead catenary systems. The consequence of issues with overhead catenary equipment results in partial sections of the track

2021年8月8日 · Since the 6th edition came out in 2021, we’ve added a new chapter explaining how electric traction works. If you download the full 6th edition here it includes that chapter. If you previously printed out the 6th edition before we added the new chapter, you can download, print and insert the extra pages in your printed copy.
