In February 2018, Deutsche Bahn unveiled its state-of-the-art, environmentally friendly maintenance facility for the new ICE 4 fleet. To facilitate a large workload with minimal downtime, the maintenance hall boasts numerous wastewater disposal shafts equipped with hose reel systems, suction guns, and water filling shafts. The outdoor areas house supply and disposal modules, along with cleaning cabinets integrated into the interior cleaning system. Thanks to the impressive capacity of Roediger® systems, up to 16 ICE trains can be serviced each night.
