Rolling Stock
Further information: London Underground rolling stockThe Underground uses rolling stock built between 1960 and 2012. Stock on subsurface lines is identified by a letter (such as A Stock, used on the Metropolitan line), while tube stock is identified by the year in which it was designed (for example, 1996 Stock, used on the Jubilee line). All lines are worked by a single type of stock, except the District line, which uses both C and D Stock. Two types of train are currently being introduced: 2009 Stock for the Victoria line and S stock for the subsurface lines, with the Metropolitan line A Stock being replaced first. The introduction of new stock for the Victoria line began in 2009, and the first S stock unit entered service in 2010.
In addition to the passenger stock described above, there is engineering stock such as ballast trains and brake vans. These are identified by a 1-3 letter prefix, then a number.

“However low and poor the taking Snuff argues a Man to be in his own Stock of Thought, or Means to employ his Brains and his Fingers, yet there is a poorer Creature in the World than He, and this is a Borrower of Snuff; a Fellow that keeps no Box of his own, but is always asking others for a Pinch.”
—Richard Steele (1672–1729)
