There is currently in Europe, though less so in the USA, a great push to remove hydrocarbon fuelled vehicles from the road and replace them with electrically powered vehicles. Thus we are seeing plug in electrical cars, hybrid cars, hybrid busses, electrical trams. But there has been no mention of trolley busses. In my youth in 1960s Bradford trolley busses were one of the major forms of public transport. They were fast and, unlike trams, had a limited degree of mobility which allowed them to pass vehicles parked on their track. I would have thought that a modern trolley bus, equipped with auxiliary batteries, would be a good alternative to a tram, being far more flexible in its routing.. But there is no proposal to reinstate them any where in Europe. I wonder why? __________________________________________ David C Brown 43 Bings Road Whaley Bridge High Peak Phone: 01663 733236 Derbyshire eMail: dcb.home@gmail.com SK23 7ND web: www.bings-knowle.co.uk/dcb *Sent from my etch-a-sketch* --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
