Fieldtrip in union station

We had a fieldtrip on last Friday in union station. This is a major train station in Washington DC. It opened in 1907. We learned too many things from there. Before I went there I didn’t know how to take the train. We also walked around the station. They have some different kinds of restaurants, clothing store and other kinds of shop. In conclusion, I really liked the fieldtrip. We had a good time.
