Track maintenance machines used for works on the overhead line system in tunnels and urban areas must be equipped with soot particle filter units when they use combustion engines to reduce diesel engine emissions.
The E³ drive technology allows machines to be operated free of any exhaust emissions.
Expanded FIELD OF APPLICATION
Due to the busy timetables, maintenance and construction works mostly have to be carried out during night-time track possessions or on weekends, leading to protests by lineside residents. The E³ drive technology significantly reduces the noise emitted on work sites.
