Overhead lines vs third rail: how does rail electrification work?

The third rail electrification system, also known as the contact rail system, provides power to trains through a conductor rail placed alongside, or between, running rails. Trains have metal contact blocks, or ''contact shoes'', which make contact with the conductor rail. Conductor rails are mostly steel (a specially conductive type).
