I took this photo a while ago on a visit to this excellent local tramway preservation organisation. It is well worth a visit.
When I was about 14 I went on a cruise with my Mum and Dad and it called in at Lisbon where we had a ride on a tram like this one. The track must have been in a poor state back then (1972) as it lurched around all over the place. So much so that as a standing passenger I fell over and in an attempt to save myself I pulled the chord to stop the tram. You can imagine how unpopular I was!
