问题 What is the existing travel time between the two cities?
Reaching a speed of 416. 6 km per hour, a new high-speed train linking Shanghai and Hangzhou set a fresh world record of train speed during its trial operation on Tuesday morning.
    At an average speed of 350 km per hour, the high-speed train is expected to cut in half the existing travel time to 40 minutes to cover the 202-km journey between the two cities.
    The train connecting Shanghai and Hangzhou, capital of East China’s Zhejiang province, is expected to start official operation in late October, according to State broadcaster China Central Television.
    "The new record of 416. 6 km per hour shows that China has achieved a new milestone in high-speed train technologies," Zhang Shuguang, deputy chief engineer of the Ministry of Railways, was quoted as saying.
    Liu Yulei, a China National Radio reporter who experienced the trial run, said she felt like she was flying when the train reached its peak speed.
