Siemens has outfitted two heavy-duty Mercedes trucks with electric current collectors and a modified drivetrain capable of operating with two different systems. When an overhead line is available, these prototypes run on electricity alone, much like electric locomotives. When there's no overhead line, a diesel engine kicks in, powering a generator that continues to supply the electric system with power.
