You can make instant noodles on the high-speed rail. The railway department has no regulations not to eat instant noodles. Although there is no explicit provision, you should try not to eat it on the high-speed train, because the high-speed train compartment is closed and the smell is too strong to be dispersed. You can choose food such as bread.

High-speed railway, referred to as high-speed railway, refers to the railway with high standard of infrastructure design speed, safe and high-speed train running on the track, and the train running speed is above 200 km/h.

Extended data

High-speed rail has different regulations in different countries, different times and different scientific research and academic fields. The National Railway Administration of China defines China's high-speed railway as a passenger dedicated railway with a design running speed of more than 250km/h (including reservation) and an initial running speed of more than 200km/h, and has issued the corresponding document "Code for Design of High-speed Railway".

The National Development and Reform Commission of China defines China's high-speed railway as a newly-built or existing railway with a speed of 200 km/h or more, and has issued the corresponding Medium-and Long-term Railway Network Planning Document, which unifies all track lines with a speed of 200 km/h into the category of China's high-speed railway network. ?

"High-speed train" is referred to as China high-speed EMU passenger train (G-prefix train) by people and train ticket system under China Railway Corporation (12306 official website), which is actually a mistake. ?

Ballastless track is widely used in high-speed railways in China, and a few of them use ballasted track. China's high-speed rail lines are unified to build electric EMU trains with a speed of more than 200 kilometers per hour. The trains are divided into three types: "starting with the letters G, D and C", and the vehicles are divided into CRH and CR series models.

At present, the high-speed railway in China is limited to the national railway line. Although the design speed of Shanghai maglev track line is 430km/h, which exceeds the railway speed standard of any country, it does not belong to the category of conventional high-speed railway because it has no national railway nature and is neither managed by the national railway department nor connected with the national railway network.
