Dennis Rapley is absolutely right to highlight the benefits of modern trolleybuses (NCE 16 February). Their role in contributing towards a stepchange improvement in urban quality of life using proven technology is recognised throughout the world.
Rome is one example of several new installations over the last few years and many other systems are being modernised and expanded.
Proper consideration of trolleybuses in the UK is long overdue.
While trams may well remain the better option on corridors with very high passenger flows, trolleybuses could bring similar advantages at lower cost in many more situations of moderate to high demand.
Those with doubts about trolleybuses would do well to visit Salzburg. All local bus routes are now entirely trolleybus operated, with routes formerly operated with diesel buses now showing 10-20% increased ridership.
The nternational ssociation of Public Transport (UITP) includes a working group to promote trolleybus operation and a joint workshop is planned for April 2006 in Salzburg. Details are at www.trolleymotion. com .
