The DT4: light and safe on the road

The first DT4 trains were in operation on Hamburg’s tracks as early as 1988. By 2005, our DT4 fleet had grown to over 120 vehicles. The HOCHBAHN carried out modernisation on this generation of trains on numerous occasions, most recently giving them a “spruce up” between 2015 and 2018: notably with a new, contemporary interior re-design. But the DT4 has a lot more to offer than simply passenger comfort. Under the bonnet too, the vehicle engines are cooled with water. This, coupled with sophisticated drive electronics, means that noise made by the trains is kept to a minimum.
