Dual-mode vehicle

Dual-mode vehicles were originally studied as a way to make electric cars suitable for inter-city travel without the need for a separate engine.

[citation needed] Similar to model trains, the ground level power supply is transported through the metal track to the vehicle.

Because of the health risks with higher voltages in real systems, the power rail is only switched on when a vehicle is covering the section, to prevent pedestrians from being injured.

Cities with slow air exchange (inversion) and high emission figures (particulate matter PM10, PM2.5, NOx, Ozone) caused by diesel-powered vehicles, need a way to reduce big pollution sources.

Commercial diesel-fueled vehicles are prime targets because of their high NOx and PM emissions caused by the lack of sufficient pollution controls.
