This IS the FUTURE in mass mobility. Not at a all an ex-eastern-bloc grim past rem(a)inder. Best Cost/Benefit ratio in overall political and financial evaluation. Flexible, safe, inviting and both citizen and local administration-friendly.
Not really, no. Modern conventional diesel buses have much cleaner and quieter engines that any past environmental and noise benefits of trolleybuses are now negligible. That and the additional costs of maintaining a trolleybus system and its drawbacks (like not being able to overtake in service or deviate from its route) has rendered them essentially obsolete. Greatly video and camerawork though :)
Modern conventional diesel buses are now regarded in the past tense, London is now going zero emission by 2025. The fixed track infrastructure hasn`t rendered trams obsolete, that same infrastructure gives a degree of permanence so people actually buy homes on the route and businesses open near the stops. Cities like Los Angeles are erecting "Obsolete infrastructure" in all directions! Just to add that this is the first of a new breed of trolleybus systems in Spain not the last! Diesel is now on borrowed time, no new diesel buses for London from 2018, Paris is banning all diesel vehicles from its roads.
