The Oyster card may have been inspired by Hong Kong's transport system, which uses the similar Octopus card. As with the Octopus card and other pay-as-you-go smartcards, also notably in Japan, there is the potential for future expansion of the Oyster card to act as an e-money payment system.
Travellers touch the card to a distinctive yellow circular reader (a Cubic Tri-Reader) positioned on automated barriers at London Underground stations to 'touch in' and 'touch out' at the start and end of a journey (contact is not necessary, but the range of the reader is only a centimetre or so). Tram stops and buses also have readers, on the driver's ticket machine or, in the case of articulated buses, near the other entrance doors as well. Oyster cards can be used to store both period travelcards and bus passes (of one week or more), and a pay-as-you-go balance.
The system is asynchronous with the most up-to-date balance and ticket data held electronically on the card rather than in the central database. The main database is updated periodically with information received from the card by barriers and validators. Tickets purchased online or over the telephone are "loaded" at a preselected barrier or validator.
Sir Edgar Speyer, 1st Baronet (7 September 1862 – 16 February 1932) was an American-born financier and philanthropist. He became a British subject in 1892 and was chairman of Speyer Brothers, the British branch of his family's international finance house, and a partner in the German and American branches. He was chairman of the Underground Electric Railways Company of London (UERL, forerunner of the London Underground) from 1906 to 1915, a period during which the company opened three underground railway lines, electrified a fourth and took over two more.
Speyer was a supporter of the musical arts and a friend of several leading composers, including Edward Elgar, Richard Strauss and Claude Debussy. He was chairman of the Classical Music Society for ten years, and he largely funded the Promenade Concerts between 1902 and 1914. His non-musical charitable activities included being honorary treasurer of the fund for Captain Scott's Antarctic expedition. For his philanthropy he was made a baronet in 1906 and a Privy Counsellor in 1909.
After the start of the World War I, he became the subject of anti-German attacks in the Press. In 1915, Speyer offered to resign from the Privy Council and to relinquish his baronetcy, but the Prime Minister turned down the offer. He resigned as chairman of the UERL and went to the United States. In 1921, the British government investigated accusations that Speyer had traded with the enemy during the war, and had participated in other wartime conduct incompatible with his status as a British subject. Speyer denied the charges, but his naturalisation was revoked and he was struck off the list of members of the Privy Council. (Full article...)
Image 4The newly constructed junction of the Westway (A40) and the West Cross Route (A3220) at White City, circa 1970. Continuation of the West Cross Route northwards under the roundabout was cancelled leaving two short unused stubs for the slip roads that would have been provided for traffic joining or leaving the northern section.

A60 stock trains operated on the surface and sub-surface sections of the Metropolitan line from 1961 to 2012 and 1938 Stock operated on various deep level tube lines from 1938 to 1988.
