Modern European systems predominantly make use of bottom or side contact power rails. There are numerous urban rail systems, including these running mostly in tunnels, which do not use third rail at all. Such systems can be found in Asia, which may have been influenced by the overhead power supply formula followed by Tokyo Metro after 1960
Third-rail systems are a means of providing electric traction power to trains using an additional rail (called a "conductor rail") for the purpose. On most systems, the conductor rail is placed on the sleeper ends outside the running rails, but in some systems a central conductor rail is used.

A bottom-contact third rail electrification system on the Bucharest Metro, Romania. Most electrification systems use overhead wires, but third rail is an option up to 1,500 V. Third rail systems almost exclusively use DC distribution.
The following is a list of all heavy rail rapid transit systems in the United States. It does not include statistics for bus or light rail systems; see: List of United States light rail systems by ridership for light rail systems. All ridership figures represent unlinked passenger trips, so line transfers on multi-line systems register as ...
conductor rail, usually a third rail to one side of the running rails. Conductor rail can be: top contact: oldest, least safe, most affected by ice, snow, rain and leaves. Protection boards are installed on most top contact systems, which increases safety and reduces these affections.
The following is a list of commuter rail systems in the United States, ranked by ridership. All figures come from the American Public Transportation Association's (APTA) Ridership Reports Statistics for the fourth quarter of 2023, [1] unless otherwise indicated.
