A new eHighway concept developed by Siemans may some day give fleets an on-demand choice between diesel and electric power. Photo: Siemens
A computer and sensors help the pantograph connect properly to the wires once extended. Photo: Siemens
Test trucks are able to maintain highway cruise speeds using only electric power. Photo: Siemens
THe hook-like component that actually makes contact with the overhead powerlines is called a pantograph. Photo: Siemens
With Siemans' system, the truck driver can raise or lower the pantograph as needed while driving. Photo: Siemens
