Lisbon
Lisbon developed from the end of years '50 a metro network, which was modified and upgraded many times. A crucial date was 1998 (the year of Lisbon Expo '98), when the network assumed the actual shape, with 4 lines (Blue Line: opened in 1959, currently 14 km long; Yellow Line: opened in 1959, currently 11 km long; Green Line: opened in 1972, currently 9 km long; Red Line: opened in 1998, currently 6 km long) for a total length of 40 km (mostly underground). The most recent line (Vermelha - Red -) was built before Expo '98 in order to connect Alameda to the exposition area. A southern extension (Alameda-Saldanha-Sao Sebastiao) opened on August 2009; another important extension from Oriente stop to the Airport opened on July 2012.
An ancient tramway network is still working, running through the hilly suburbs (Alfama, Barrio Alto, etc) and the city center (Baix). 4 of the lines (12,18,25,28) adopt old Brill rolling stock (built from 1936 to 1940), which was renewed to preserve its original features. A fifth line (n. 15) runs along the river side and utilizes modern rolling mono-directional low-floor trams.
The first stretch (Corroios-Cova da Piedade) of a modern LRT line (MTS-Metro Transportes do Sul) opened on 30 April 2007, using Siemens Combino rolling stock; the whole line once completed will connect Almada to Seixal (in the southern part of the city), with many interchanges point with local railways and the ferry-boats net.
