The British Rail Class 360 Desiro is an electric multiple-unit class that was built by Siemens Transportation Systems between 2002 and 2005. The Class 360 is currently operated by East Midlands Railway and the Global Centre of Rail Excellence. Description Class 360/1 First Great Eastern ordered 21 four-car Class 360/1s to replace its slam-door Class 312 units. Built in Krefeld, Germany, the units feature air conditioning, plug doors, CCTV, a wheelchair area, and first class at the cab ends. After being tested at the Wildenrath, Germany and Velim, Czech Republic test tracks, the first entered service in August 2003. In February 2004, unit 360115 returned to Wildenrath for tests aimed at improving pantograph performance. They were primarily used on Great Eastern Main Line services from London Liverpool Street to Clacton-on-Sea, Colchester Town and Ipswich. They also ran to Walton-on-the-Naze and the Mayflower line. They occasionally operated through to Norwich. In April 2004, the Great Eastern franchise was merged into the Greater Anglia franchise that was awarded to National Express East Anglia. All passed with the franchise to Greater Anglia in February 2012. The Class 360s were not maintained by the franchisee, but under contract by Siemens at Ilford EMU Depot.
