Jubilee line
Jubilee line trains use platforms seven and ten, which opened in 1979 when the newly built Jubilee line took over existing Bakerloo line services to Stanmore running through new tunnels from Baker Street to Charing Cross to serve as a relief line to the Bakerloo which by now was suffering from capacity issues. In 1999 the Jubilee line was extended from Green Park to Stratford and made the Jubilee line platforms at Charing Cross redundant after twenty years The design of the Jubilee line platforms at Baker Street has changed little since being opened with illustrations depicting famous scenes from Sherlock Holmes cases.
