A trolleybus wouldn't be able to divert along an unwired road. They're also a nuisance when the pickup arm gets disconnected from the wires. |

How's the battery bus with charging pad in Walthamstow getting on? |

Many of them have a small generator or battery for precisely that purpose. They're also a nuisance when the pickup arm gets disconnected from the wires. It's not hard to put it back on using the ropes at the back. Neil -- Neil Williams Put my first name before the @ to reply. |

I've never heard of that and can't imagine how it might work thinking of dewirements I observed in London and later in Brazil. Given the state of image recognition software these days I image having a camera that can spot the wires and then align the booms up with them would be entirely possible. Or just keep trying blind until the power comes back on. It wouldn't take so long or be needed so often to be worth putting in extra intelligence. Does any city put Regent-Street-style Christmas decorations over tram/trolley wires? Pretty sure that's a yes. Here in Buc the adage 'less is more' is never applied to Christmas lights, and they're strung over more or less every major street (they make Regent Street look like a set of Argos LED tree lights) - and we have both trams and trolleybuses. L'viv also has both trams and trolleybuses and has lights strung across the streets at Christmas, if I recall correctly. Moscow goes for lights in a big way (albeit more in honour of New Year than Christmas,) although in my observations mostly around pedestrianised streets and squares rather than across the road as such. Next year I'll take a closer look and report back ))) |

Perhaps not as elaborate as Regent St, suspended Christmas lights above Bahnhofstrasse are a feature of the Zürich decorations, and Bahnhofstrasse has pretty intensive tram service along its length. https://newinzurich.com/2014/12/chri...-hours-zurich/ Robin |

My experience of dewirements was that the booms were restored pretty quickly, especially given that London trolleybuses never had trolley ropes. -- Colin Rosenstiel |
