Talk:Trolleybuses in Glasgow

Untitled
So what makes a trolleybus distinct from the cities buses etc? There is no mention in the article of what defines a trolleybus. 217.46.243.106 (talk) 09:23, 1 August 2011 (UTC)
 * At it's simplest its an electrically powered bus with rubber-tired wheels (US spelling for tires) that takes its power from electricity cables/wires in the street, sited above both the road surface and that of the roof of the trolleybus, by means of a rotatable "pole" mechanism on the roof. On the end of the "pole" is a device which electrically connects the trolleybus to the wires, it is known as a "trolley wheel". The trolleybus can only go where those wires are and it can switch wires, it can only deviate from the line of the wires by the amount of "play" in the "pole"/trolley wheel mechanism. If you look carefully at that photo with a green/cream/orange "bus", you'll see the wires above the "bus" and the "pole". They (the wires) run along the line of the street but are supported by cross wires fixed to pairs of poles on each of the two pavements. Pyrotec (talk) 10:00, 1 August 2011 (UTC)
