The Gornergratbahn has always been electrified, and is one of four lines in the world using three-phase electric power.

This was the first commercial application of three-phase electrical power in the United States and probably the world.

Its success led to the widespread adoption of three-phase power, in preference to single-phase and direct current.

Unfortunately, the site was not wired for three-phase power, as is usually the case with television transmitters.

The three phases (or stages) have no connection with three-phase electric power.

The line is one of four lines in the world using three-phase electric power.

Today, most grids adopt three-phase electric power with alternating current.

That was not the only change, however - they were the first Kleinprofil trains to use three-phase electric power.

It used the new three-phase electric power, which would be used on all future models as well.

Unbalanced three-phase power can damage the equipment that it is meant to operate.
