Russia´s First High Speed Train Sapsan, Moscow To St. Petersburg

Short-distance trains
• Commuter trains
For shorter distances many cities have networks of commuter trains, serving the city and its suburbs. Trains are a very efficient mode of transportation to cope with large traffic demand in a metropolis. Compared with road transport, it carries many people with much smaller land area and little air pollution.
Some carriages may be laid out to have more standing room than seats, or to facilitate the carrying of prams, cycles or wheelchairs. Some countries have double-decked passenger trains for use in conurbations. Double deck high speed and sleeper trains are becoming more common in mainland Europe.
