With such a large rail network, there is always something to build, which is why we cannot do without our construction vehicles and machines. But we can certainly do without exhaust fumes. In order to minimize the impact on the environment and local residents, we only use low-emission vehicles and construction machines on our inner-city construction sites. They cut soot particle emissions by up to 90 percent.
At Frankfurt central station we have used only electric construction machines for our construction site. Electric wheel loaders, a hybrid excavator and a fully electric mini excavator were being used to dig a trench about 500 meters long in the station's cable tunnel. The electric construction machines make extraction systems and filters in tunnels unnecessary and show that we are taking innovative construction site development very seriously.
