Trams won't replace cars but they could help reduce car trips and reduce the number of cars on the roads.

Trams may sound old-fashioned, but this mode of transport is in fact more attractive today than it's ever been.

However, cost and construction time is a major hurdle to introducing trams. Tram infrastructure is expensive.

There is a cheaper, hybrid alternative called the trolleybus. It's a bus that runs on electric overhead lines so no need for tracks in the road like a tram.

Examples of the trolleybus can be found all over the world. But in many countries they fell out of favour and were scrapped.

While the trolleybus has it's disadvantages (the visual clutter of overhead lines being just one of them), maybe it also deserves a fresh appraisal?
