The generic term used by the International Union of Railways for the technology is overhead line. [1] It is known variously as overhead catenary, overhead contact line (OCL), overhead contact system (OCS), overhead equipment (OHE), overhead line equipment (OLE or OHLE), overhead lines (OHL), overhead wiring (OHW), traction wire, and trolley wire.

Building and restoring public transport centers, including commuter and light rail. When transit authorities partner with L.K. Comstock, they get the experience needed to successfully build OCS systems, third-rail systems and more.

Have you ever seen a passenger train being pulled by freight locomotives or classic streamlined diesels on a class one railroad and wondered what was up? Well wonder no more! This video will give...

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.

Once you have accessed the online course, no cancellations or refunds are permitted. This course will provide an introduction of typical light rail and commuter rail traction power systems.

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.

2024年11月20日 · Learn about key OCS components—contact wires, catenary systems, insulators, and more—and their impact on sustainable urban transportation. Explore how MAC-IMPulse LLC drives innovation with durable, made-in-the-USA OCS solutions, supporting cleaner, efficient rail systems globally.

2024年10月3日 · An overhead catenary system (OCS) is a key part of electrified rail networks and is responsible for delivering electrical power to trains. It consists of a network of wires and supporting structures designed to transmit high-voltage electricity from a power source to the train’s pantograph.

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.

problems in over-head contact system (OCS) design. However, OCS design procedures and principles can be applied at such loca-tions to provide both economic con-struction and trouble-free vehicle op-eration. SPIDER has been developed as a software tool to facilitate OCS design at complex intersections The program is interactive and permits effi ...
