Energy-saving measures
Alongside generating sustainable energy, we also want to use less energy. Approximately 90% of the electricity NS consumes goes towards running, heating, cooling and lighting the trains. The remaining energy is used for stations and offices, where we are also working hard to keep consumption as low as possible.
More people travelling by train during off-peak hours
The most efficient way to use energy is to carry more travellers during times when there is still space on the train. That is why NS encourages travelling during off-peak hours by offering discounted season tickets.
Lower energy consumption by trains
Our modern trains, such as the Sprinters and refurbished double-deckers, use less energy than their predecessors. When purchasing and overhauling trains, we pay close attention to energy efficiency. For example, trains feed braking energy back into the overhead lines. Trains nearby then use this electricity.
NS employees Jos and Rob devised a clever system to test old train motors for energy efficiency.
The modernised double-deckers feature a more efficient climate control system and smart lighting that automatically dims in response to daylight. The skill of our train drivers also helps save energy. By departing on time, accelerating smoothly and coasting to a stop, drivers reduce electricity use. We switch off trains when parked to avoid unnecessary power consumption.
Outside peak hours, many trains run empty. NS employee Jasper and a team of experts plan the most efficient timetable to address this.
Energy-efficient and climate-resilient buildings
When developing new stations, NS collaborates with the Bureau Spoorbouwmeester and ProRail to create a checklist of requirements for new stations. Alongside sustainability, we also focus on climate resilience. Will the building still perform well under changing weather conditions?
For renovations and refurbishments, we choose sustainable materials and systems, such as energy-efficient materials, cooling doors and smart meters in retail units. We also encourage energy-saving behaviour among shop staff and office employees, such as closing off certain office floors during holidays.
Escalators are major energy users at stations. NS employee Christel shows how to prevent ‘ghost escalators’—escalators running unnecessarily.
