Elevated Track and Structure Systemwide
- Funding will be targeted at preventive maintenance projects for various Infrastructure units such as Track, Structure and Power. When certain maintenance tasks are needed to repair or replace asset components in order to maintain the working life of rail system, specific component campaign work is conducted. Capital maintenance work is targeted at the following areas: Elevated Track and Structure - repair/rehabilitate track and structure elements in order to eliminate slow zones and upgrade the right-of-way along the elevated structure throughout the rail system. Traction Power Substations - program that repairs and upgrades equipment at various traction power substations currently in service. Tactical upgrades correct deficiencies and avoid service reductions due to failure and overload of aging equipment. Third Rail and Heavy Traction Power Cables - Preventive maintenance work is performed where necessary to repair/replace heavy traction power cables that feed the third rail along the tracks currently in service at various locations throughout the rail system. Rail Signal Systems - Program provides for signal equipment repair along the rail right-of-way, signal equipment on rail cars, and the reconstruction of electronic components of the signal system, including relays and circuit boards. As necessary dedicated small renewals and system modifications are also completed. All work is planned/performed to maintain the asset(s) in proper working order through its quarter life cycle, while a more extensive rehabilitation is planned at the mid-life of the asset.
