Central Railway Station gets off at GRAND CENTRAL Station, which is accessible on Line 4, 5, 6, 7 and S. This railway station is very large, luxurious and magnificent. The building is rectangular, two-storey, with steps leading to the platform, and some to the restaurant. At first glance, I saw the famous four-sided clock, less than one meter in diameter. Below it was a small house, a customer service center. The top of the sky is blue and very high. Although there are many moving passengers, it is not crowded. I want to know some information about the four-sided clock. The old lady in the Information Center said humourously that you can check it online. I know it's very expensive. Are you going to buy it? She said, shrugging and laughing, and handed me a set of timetables. On the second floor, there is Apple's flagship store. Many Apple products are on the table for customers to experience. The Internet speed is very fast. Two rooms, one with a stool. Waiting for the train, traveling can come to the Internet at any time to inquire or kill time. I checked the tweets there and sent some tweets.
