Six-year-old James Apps gets a close-up look at a map of the Tube as it will look in 2020, one of five LEGO Tube maps currently on display in London. The maps depict the evolution of the Tube network from 1927 through what it will look like in 2020, including Crossrail, and the proposed Northern Line extension and proposed Croxley Rail Link. The maps – each of which contains more than 1,000 bricks and took professional LEGO builder Duncan Titmarsh four days to build – can be found in the ticket halls of the following stations – South Kensington (1927), Piccadilly Circus (1933), Green Park (1968), Stratford (2013) and King’s Cross (2020).
