At Elmers End, there are two systems of electrification - the Southeastern services on the Hayes branch platforms operate via the 750V direct current third-rail power supply, and the London Trams, formerly Tramlink, services from the terminus platform also operate from a 750V direct current system, but from an overhead-wire power supply. This coexistence of third-rail and overhead-wire power supply systems is also in evidence at Acton Central, which is also a DfT Category D railway station - albeit using 25kV alternating current overhead wires instead of 750V direct current.
