What is the difference between G and C prefix trains?

[LaEvelyn]

C prefix trains are either intercity EMUs or regular trains, while G prefix trains are high-speed rail, with differences in speed and tracks. Here is relevant information: Speed difference - C prefix trains (intercity EMUs/regular trains) operate at 80-160 km/h, whereas G prefix high-speed trains run at 250 km/h. Track type - C prefix trains run on ballastless tracks (stone-free rail beds), while G prefix high-speed trains operate on dedicated high-speed rail lines. G trains have longer routes, primarily serving interprovincial travel (e.g. Guangdong to Beijing routes crossing multiple provinces). High-speed rail stations are typically located in peripheral urban areas with transportation networks.
