Baker Street is a London Underground station at the junction of Baker Street and the Marylebone Road in the City of Westminster. It is one of the original stations of the Metropolitan Railway, the world's first underground railway, opened on 10 January 1863. Although the decorations inside this station are quite worn out and look very dated, it still functions normally today due to the good management and maintenance of the subway operator, and people's love for the entire station environment. I think this is also a manifestation of sustainability.
