Metros are high capacity, high frequency, urban electric transport railway systems. Also known as the subway, underground, and tube, they are distinguished by being separated from all other types of traffic, pedestrians included. When it comes to energy consumption and space occupancy, metros are among the most efficient means of transportation. In 2006, 155 million people traveled by metro every single day.

MetroRail 2010, held at the end of March, was the 6th annual conference bringing together worldwide leaders of the public transportation industry. The Metros are awards given at the event to recognize the top metro companies.

We've compiled information on the 2010 Metro Awards winners, and highlighted some other notable metros. Vote for your favorite!
