Electric Car 274 - seen here in Foz do Douro. This is/was one of the trams which ran the number 1 route from Passeio Alegre to Infante along the northern bank of the Douro River.
The tram was built in the early 1900s by the British United Electric Car Company and for this reason is sometimes known as the "English" car. It began operating in Porto in 1909 but is now semi-retired as part of the Porto Tram Museum (Museu do Carro Eléctrico) collection.
