There is always something to do on a rail network as big as ours. That's why we take steps to ensure the air stays clean even on our construction sites. In order to minimize the impact on the environment and local residents, we only use low-emission vehicles and construction equipment on our inner-city construction sites. They cut soot particle emissions by up to 90%.
We also make use of electric construction equipment on our construction sites. At Frankfurt Central, an electric wheel loader, a hybrid excavator and a fully electric mini excavator were used to dig a trench about 500 meters long in the station's cable tunnel. We are testing a fully electric working platform for use on our construction sites as we work on building the S 21 line in Berlin.
Using electric construction equipment ensures clean air and eliminates the need for extraction systems and filters in tunnels. Their low noise emissions are an added bonus.
