Editor's note: Starting Dec 23, the Beijing-Shanghai high-speed railway will offer a quiet carriage trial service to create a more tranquil and comfortable environment for passengers, according to the country's railway operator. Do you think quiet carriages are needed on trains? Should quiet carriages be expanded to all trains? Readers share their opinions.

I like peace and quiet. The overwhelming majority of people are well-behaved and courteous but some people just don't have any respect for others. I once had to endure sitting next to someone who made at least 10 phone calls all the way from Beijing to Shanghai. He was shouting in the phone in a language I did not recognize. I had to go to the dining coach to escape the noise.
