All PTEs share the same key roles, as outlined in 'What are PTEs'. At the same time, each PTE is unique and has evolved differently, taking on additional roles to match local circumstances and transport needs. This section provides a brief overview of some of these special features to highlight the differing contexts in which our members operate.
 | Centro (West Midlands PTE) is the largest of the PTEs, covering a population of 2.6 million people. Centro owns, promotes and develops the Midland Metro light rail network which operates between Birmingham and Wolverhampton. For more information, visit Centro's website. |
 | Merseytravel (Merseyside PTE) serves 1.4 million people. It is unique among the PTEs in being the franchisee of the local rail network, Merseyrail. It also owns and operates Mersey Ferries and Mersey Tunnels, enabling people to get across the River Mersey.

 | Metro (West Yorkshire PTE) covers a population of 2.2 million and has led the way in rolling out real-time information for bus passengers via its ‘yournextbus’ system. Metro also runs the innovative ‘My bus’ yellow school bus scheme. For more information, visit Metro’s website. |
 | Nexus (Tyne and Wear PTE) serves a population of just over 1 million people. It owns and manages the Tyne and Wear Metro, the first of a new generation of modern light rail systems in the UK and now the most used light rail network in the country outside London.
