In Lisbon they have old trams in daily use - some dating from the 1930s.  

This one has just passed the frontage of the Se Cathedral - the trams are electric and the oldest single car ones travel the most challenging routes around the city up and down the steepest hills and around the tightest corners - the new modern trams are confined to the flatter parts of the city.

The E28 route trams track over the hills and are popular with tourists - particularly so as the streets in the older part of the city are very steep and for those, like me, from a county with nearly half of its total area both flat and below sea level a little mechanical transport is a welcome relief from all the steps between streets.
