I see that you will travel from Beijing to Shanghai by train. But the thing is that there are more than one railway stations in both Shanghai and Beijing. In this case, you need to tell which railway station in Beijing you will depart from and which station in Shanghai you will arrive at. You may see the detailed info at China Trains(https://www.travelchinaguide.com/china-trains/). Then people can tell you how you may get to the railway station in Beijing from your place and the address of the specific Shanghai railway station.
