London Underground 1967 Stock in time for the 150th anniversary of the London Underground, in 2013. However, refurbished driving motor car 3186 has now been preserved at the site, in experimental condition with a dark grey rather than white car end, and narrower transverse seating. The 1967 stock was used as the tube train design for the Royal Mint's special £2 coin designs of 2013 marking the 150th anniversary of the London Underground. Motor cars 3079 and 3179 are now part of the Asset Inspection Train, sandwiched between two cars of 1972 stock on either side and without the wrap-around cab windows. London Underground
