Both systems live edit

The system is usually used only in exceptional cases as it can lead to problems caused by the interaction of the electric circuits; for example, where one system is powered with direct current and another by alternating current (AC), premagnetisation of the substation transformers of the AC system can occur.

One system live edit

A similar arrangement to dual electrification is one in which both means of powering a train are present, but not live simultaneously. Such arrangements can be found in frontier stations and in sections of railway used for running tests.
