The London Underground is a public transport network, composed of electrified railways (that is, a metro system) that run underground in tunnels in central London and above ground in the city’s suburbs. The oldest metropolitan underground network in the world, first operating in 1863, the London Underground is usually referred to as either simply «the Underground» by Londoners, or (more familiarly) as «the Tube».

The Tudor rose (sometimes called the Union rose) is the traditional floral heraldic emblem of England and takes its name and origins from the Tudor dynasty.
When Henry VII took the crown of England from Richard III in battle (1485), he brought about the end of the Wars of the Roses between the House of Lancaster (which used the badge of a red rose) and the House of York (which used a white-rose badge).

Henry’s father was Edmund Tudor from the House of Richmond, and his mother was Margaret Beaufort from the House of Lancaster; in January 1486 he married Elizabeth of York to bring all factions together. (In battle, Richard III fought under the banner of the boar, and Henry under the banner of the dragon of his native Wales.) The white rose/red rose idea was a Tudor invention.
