be modified and equipped with half-height platform gates (full-height doors on the new underground stations) to provide level boarding and minimize the gap with the train. Refurbishment and expansion work on platforms and stations will also be carried out. Admiralty, Diamond Hill and Hung Hom stations, all of which are major interchanges following full opening of the new lines, have been expanded or relocated to cater to increased demand. New rolling stock The East West Corridor will operate using a combination of both new and existing rolling stock, while the North South Corridor will have its existing rolling stock fully replaced with new stock. Contract 1141A for 17 8-car C-Trains for the East West Corridor was awarded to CRRC Changchun Railway Vehicles in December 2013. Designed in 14 months, the first train, officially named East West Line Train, arrived in Hong Kong in June 2016 and began passenger service on the Ma On Shan Line on 12 March 2017. Contract 1141B for 37 9-car R-trains for the North South Corridor was awarded to Hyundai Rotem of South Korea in December 2012. The first delivery took place in 2015 with all new trainsets in service by 2020, fully replacing the 12-car Metro Cammell EMUs which were already retired. Contract 1151 for 36 additional SP1900 cars was awarded to Kinki Sharyo of Japan in January 2014. They are being used to convert all SP1900 trains into 8-car formations to serve the East West Corridor. Previously, they have operated in 4, 7, and 12-car formations on the existing lines.
