I was interested in the tram - Mum and I went to the Wirral a couple of months ago and ended up in New Brighton but we basically followed signs through Birkenhead and didn't see it.
The tramway runs for about a mile or two from the ferry terminal to the transport museum. Normally it is operated by trams which were built by Hong Kong Tramways in heritage style but are actually only about fifteen years old. Because it was a special vintage transport day they had four historic trams running. I've created a new album set about the Birkenhead Tramway on my website with pics of all the trams which were running while we were there.
