Moscow is the capital of Russia and has approx. 12 million inhabitants. The 12 metro lines run on a network of almost 350 kilometres length usually in a 1.5 to 3 minutes headway. The Moscow metro is regarded as the fastest subway of the world at an average station distance of 1.8 kilometers and a maximum speed of 100 km/h. The line No. 3 has the longest route length: 45 kilometres, which is covered in only 67 minutes.

The tram system has a length of more than 180 kilometres, its track gauge is 1,524 millimetres. The tramway network was divided into two parts by builing a new metro line in 1973. Since then, the northwestern part of the network, which covers about 25% of the complete network, has no more connection to the main part.

While trams and buses are operated by the municipal transport authority → Mosgortrans (Мосгортранс), a company named → Moskowski metropoliten (Московский метрополитен) was founded for the operation of the metro. Nowadays, there are tickets available which are valid at both operators. It is not anymore required to obtain separate tickets for metro and the other means of transport.
