A trolleybus of the optically-guided trolleybus system of Castellón de la Plana, Spain. The system is named "Tram" (or TRAM), for Transport Metropolità de la Plana, but is not a tram system. In this photo, the vehicle had reached the end of the overhead trolley wires, and the driver has lowered the trolley poles (causing them to be hidden from view by the cowling along the roof, with only the outer ends of the two poles visible, at the rear of the vehicle), and the trolleybus will proceed from here on battery power.
