I would like to travel on the high speed train from Puntong Internatio

Do you mean Pudong International Airport in Shanghai? If yes, you need to take train from Shanghai Railway Station to Enshi and the 3 trains depart from 08:01 to 09:14. It takes about 8-9 hours to get and takes CNY 489 for a second class seat.

From Pudong airport to Shanghai Railway Station, you need to take Metro Line 2 to Century Avenue first and then interchange to Metro Line 4 to the station. It takes about 1.5 hours and costs CNY 7.
