Quote: "London Underground is celebrating its 150th anniversary this year,
and Lego has marked the occasion by recreating five Tube Maps made entirely
out of Lego bricks that will be displayed in major London Underground
stations throughout the summer months.

The five Lego Tube maps show how the network has evolved over the years
starting from 1933 through to the future, 2020. From 12 June, these Lego
maps will be displayed in ticket halls of major London Underground
stations. You can check them out at:

South Kensington - 1927
Piccadilly Circus - 1933, Harry Beck’s original map
Green Park - 1968
Stratford - 2013
King’s Cross - 2020, including Crossrail, the proposed Croxley Rail Link
and the proposed Northern Line Extension
Lego Tube Map – the vital statistics

Each map is made up of over 1,000 Lego bricks
The Lego Tube maps measure 140cm x 100cm
Each map took four days to build
Created by Duncan Titmarsh, the UK’s only Certified Lego professional –
there are only 13 in the world!"
