A number 18 tram trundles its way along the riverside in Porto. The 18 tram route is quite short but involves climbing the rather massive hill that is Rua da Restauração. The route starts at the Porto Tram Museum, which was the old tram station, in Massarelos and ends at Carmo.
This is tram 205. The number suggests it was one of the Brill 28 "Plataforma-Salão" trams built in the late 1930s / early 1940s by CCFP (Companhia Carris de Ferro do Porto).
