Atocha Railway Station in Madrid is another place to visit freely. The old railway station built in 1851 is still in normal operation, which is the main reason for attracting us to visit. Looking from its outside, the red wall and the black dome have no obvious sense of vicissitudes. Its interior is full of vitality because of its green color. The terrorist attacks of 2004 made it even more famous in the world. Looking at the train going in and out of the station, I can't help thinking of Shanghai Laobei Station. There are not necessarily some parents. People are glowing with youth. The weeds in Shanghai North Station have covered the railway tracks. The green grass in Atocha Railway Station has also brought more popularity to restaurants. One drawback is that the station is slightly stuffy, perhaps because the air conditioning is not on. Maybe tropical plants need it.
