Taxi from Tianjin Cruise Ship Port to Train Station to take Bullett train to Beijing?

It is not suggested to take a taxi from the port to the railway station direct, because there is about 45km between the two places.
There are a lot of taxis waiting there, so please do not worry about it. You can take a taxi from the port to reach Citizen Square and then take the Light Rail toa reach the railway station directly.

Thank you for the information but I cannot do stairs and walking is a bit difficult so we wanted to take a Taxi from the port directly to the Train Station. Also we will have luggage with us. Will a Taxi take us there? How long would it take to get there and how much would it cost? If we took the "Light Rail" is this a subway? Are there stairs? Maybe there is a bus that goes directly from the port to the Train Station? Please let me know and thanks again for you information. It is very helpful!

Yes, the taxi can take you to the train station and the whole journey cost you around 150RMB. It takes about an hour to an hour and a half.
The Light Rail is a kind of subway and there are stairs.
There is no direct buses between the two places. So if do not wnat to take the Light Rail, you can take a taxi directly.
