China Railway CRH6

The CRH6 is a regional/commuter higher-speed train of the People's Republic of China. It is designed by CRRC Qingdao Sifang and will be manufactured by CRRC Nanjing Puzhen at its subsidiary, the CRRC Guangdong Jiangmen Factory. Unlike other CRH types, most CRH6 trains use unique names; only very few CRH6 use Hexie as the train name.

Overview
The CRH6 will be divided into three major types, according to stopping patterns:
 * CRH6A is the higher speed version with a designed top speed 250 km/h, top operating speed 220 km/h to be used on regional non-stop or express services. It uses a 2+2 transverse seating layout using reversible seats that have a similar level of comfort and space to that of intercity trains. There is a toilet on cars 1, 3, 5, and 7.
 * CRH6F is the High-speed rail version with a designed top speed 180 km/h, operating speed 160 km/h to be used on express commuter services. It uses a 2+2 transverse seating layout with non-reversible seats that have a similar level of comfort and space to that of a suburban train. There is a toilet on cars 3 and 6.
 * Metropolitan area EMU based on the Cinova intercity train platform (Chinese: 基于Cinova城际列车平台衍生的市域动车组) with a designed top speed 140 km/h, to be used on local commuter services. It will feature longitudinal seating arrangements similar to that of subway trains with more and larger doors for faster boarding and alighting.

On December 29, 2009, the MOR ordered 22 sets of 160 km/h class and 10 sets of 200 km/h class 6-car Intercity High Speed train from CRRC Puzhen, the contract worth 2346 million RMB, and now the order has been transformed into 24 sets of CRH6 and will be delivered by the end of 2012.
