Dear Tanusree,
Greetings from Sophie, Top China Travel!
Thank you very for attention with your questions. Your question is"Is the high speed train service closed?"
I wonder what you mean. high speed trains in China are still working and it has already been the main transportation way in China and future. China government does not close high speed train.
I guess whether you would like to book high speed train tickets or not. If you mean you would like to book high speed train tickets, may I know below information so that we could check the availability and price for you.
1) When will you hope to take high speed train?
2) From which city to which city do you hope to take high speed train?
3) How many of you hope to take the high speed train?
4) Do you need any other service, such as tours, transfers, hotel booking, domestick flights booking, ect.
Hope the above is clear and helpful.
Should you have any further questions,please do not hesitate to contact with us.
Best regards
Sophie Huang
