Is it comfortable to ride on the train with the letter “c”?

Comfortable. C-shaped trains have very spacious seats, and each seat can be tilted backwards to make passengers more relaxed and comfortable. The distance between seats is also very wide, and passengers can have enough space to stretch out, which is very comfortable. The train prefixed with c means intercity train. In fact, this is a special type of domestic passenger train. It starts with the letter C and is followed by a series of numbers.
