[Q]: Question: Which of the cities in Austria with tramway systems has the smallest population? Passage:In Austria, Gmunden, Graz, Innsbruck, Linz and Vienna all have tramway systems. With 173.4 km of track, Vienna's network is one of the largest in the world. The cars have been constantly modernised over the years and many are now ultra low-floored. Many of the Austrian tramlines have been in constant operation since they were first opened. Vienna started with horse trams in 1865 and electrification followed in 1897. Graz had horse trams in 1878 and electric cars in 1898 while Linz goes back to 1880 with electrification in 1897. The Gmunden Tramway, only 2.3 km long, is currently one of the shortest in the world, and with gradients of up to 9.6%, it is also one of the steepest and has become a popular tourist attraction. Innsbruck, which traditionally used second-hand trams from other cities, replaced its whole fleet with 32 Bombardier low-floor cars in Summer 2009. The Pöstlingbergbahn, in Linz, an unusual "mountain tramway", has a gradient of 10.6%, which makes it one of the world's steepest gradients on a surviving adhesion-only railway. The tramway now reaches the city centre via the tracks of the urban tram system.
