Deutsche Bahn is committed to reducing its greenhouse gas emissions across the entire value chain to net zero by 2040. A key element of this strategy is increasing the share of green electricity. Since early 2025, all stations, maintenance depots, office buildings, and sites supplied by DB Energie have been powered with 100 percent green electricity within Germany. In addition, DB ensures that the energy used is as efficiently as possible.

One example is the plattform displays. These displays require electricity to inform passengers about arriving and departing trains. Thanks to an intelligent energy saving mode, consumption can be reduced to a minimum. 

Lights off – climate protection on 

Especially at night and during operational breaks, there are long periods when the displays are not needed. To save energy, an energy saving mode is activated wherever safety regulations allow. When active, the displays’ backlighting is dimmed or turned off entirely.

Passengers continue to receive all necessary information on the platform because the energy saving mode is integrated with real-time updates. For important announcements or alerts, the displays immediately wake up. This way, the displays use only a small fraction of the energy they would in normal operation, saving thousands of kilograms of greenhouse gas emissions each year.

More displays with energy saving mode 

In 2024 around 2,000 of the roughly 5,000 plattform displays are already equipped with the technical capabilities for energy saving mode nationwide — and the number is growing. When old devices are replaced or new displays installed, this function can be configured from the start.
