Electrification

Railway electrification systems supply electric power to trains via overhead lines, third rail or ground-level power systems. Overhead line equipment (OLE) is typically used on mainline routes, while third rail is common on metro and suburban networks. Ground-level power supply systems are also used, particularly for trams, and are only energised when in contact with the vehicle. Suppliers in this category provide design, installation and maintenance services for railway electrification infrastructure.
