Track Renewal Train
A track renewal train (also known as a track renewal system or new track construction machine) is a work train that consists of many units of machinery and materials required for track renewal (rail and sleeper replacement) projects. Rail preparation To minimize the time of track during a track renewal project, a track renewal train is used to automate most of the required process. Prior to the arrival of the track renewal train, preparation tasks must be completed. In some cases, the old rail needs to be cut into smaller segments and joined with fishplates. The rail fastening system may need to be released prior to its arrival. The new rails usually need to be prepared prior to the arrival of track renewal train. Rails are delivered to the center of the track. Those rail pieces are welded by track workers to form continuous welded rail (CWR) and left at the center of the track at the exact position required by the track renewal train to pick up at its arrival.

Maintenance Of Way
Maintenance of way (commonly abbreviated to MOW) refers to the maintenance, construction, and improvement of rail infrastructure, including tracks, ballast, grade, and lineside infrastructure such as signals and signs. Track The most fundamental maintenance of way task is the construction, repair, and replacement of the track and its supporting ballast and grade. The task was once done entirely by manual labor, but in the 21st century, track maintenance is largely done by specialized machines that are much faster and require fewer people to accomplish the same amount of work. Electrification systems On rail lines, which include electrification by a third rail or an overhead line An overhead line or overhead wire is an electrical cable that is used to transmit electrical energy to electric locomotives, trolleybuses or trams. It is known variously as: * Overhead catenary * Overhead contact system (OCS) * Overhead equipm ..., maintenance of way work includes repairing an ...
