We want our trains to last for a long time, which means we need to regularly clean and maintain them. To save resources and prevent waste when we do so, we use refillable spray cans at many of our depots, such as Leipzig, Frankfurt, Munich, Bremen, Stuttgart and Trier.
When the spray cans are empty, they are returned to good working order at our filling stations. Some cans simply run out of gas after a while because they are low on propellant. All they need is topping up with compressed air. Using compressed air, which is a natural propellant, does not result in harmful emissions and therefore protects the atmosphere.
Thanks to these measures, we have cut our usage of spray cans by around 1,400 units a year at our Leipzig depot alone.
