Regenerative Braking
On 9 November 2006, unit 357 028 was sent to the Velim railway test circuit in the Czech Republic for safety testing to obtain certification for a regenerative braking system which had been trialled for many months on the Class 357 fleet. In March 2007, 357 028 returned from the Czech Republic, having gained safety certification, and c2c began fitting the regenerative braking systems to the rest of its Class 357 fleet, becoming the first UK train operator to do so. On 3 June 2007, the eve of World Environment Day, unit 357 010 was given an all-over green vinyl sticker livery with magenta doors and the tagline: "All c2c trains are greener now - find out more at - www.c2c-online.co.uk - c2c - the greener way to go" to highlight the completion of the scheme, which has given energy savings of up to 21%. 357 010 lost its green livery in March 2011 as part of the fleet's corrosion repair and repainting project.
