What is the difference between Harmony CRH C and G series?

[OAlyssa]

High-speed rail C and G series have the following differences: Intercity characteristics: C-series trains emphasize the intercity nature of passenger trains, which is unrelated to speed. The C-series trains between Beijing and Tianjin can reach speeds up to 310km/h, while those between Guangzhou and Shenzhen only reach 190km/h. D-series trains do not have intercity characteristics, with speeds exceeding 300km/h. C-series trains are a new type of passenger train that emerged after China entered the high-speed rail era, specifically serving intercity railways or express intercity transport within trunk railways. Different journey durations: C-series trains are intercity EMU (Electric Multiple Unit) trains, generally operating on short-distance routes with journey durations not exceeding 2 hours. D-series trains typically operate on long-distance routes.
