Our operations facilities have to run around the clock. Even when there is a power failure. Because our signaling systems, stations and radio communication bases have to be in service at all times. Therefore, in the event of a power failure, standby power systems take over.
Diesel-powered generators used to fulfill this function but today fuel cells are increasingly being used. These environmentally friendly cells use hydrogen and oxygen to generate power without producing CO2 as a waste material. In ecological terms, fuel cell technology really comes into its own when the hydrogen required is produced by green sources as well.
