I was in Lisbon last weekend and managed to get some photos of some trams and trains while I was there...
First, some photos of trams on the city's streets. The track gauge is 900m or 2ft 11 7⁄16in.
A quick snap of a metro train.
And some shots taken at Gare de Lisbonne-Santa Apolónia. The mainline gauge in Portugal is the same as in Spain - 1,668 mm or 5ft 5 21⁄32in (Iberian Gauge).
(That logo looks oddly familiar...)
(These coaches look very like the old Inox coaches formerly operated by SNCF)
(Two EMUs waiting to depart. The one on the right is a double-decker unit).)
(The station pilot. Pretty sure this is an English Electric loco, judging by the bogies and the whistle from the engine.)
A couple of shots taken around the area of Belém, where the railway runs between two parallel roads...
And finally, a shot of Gare do Oriente taken from the outside at night.
