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.

Famous quotes containing the words rolling and/or stock:
“I caught this morning morning’s minion, king-
dom of daylight’s dauphin, dapple-dawn-drawn Falcon, in his riding
Of the rolling level underneath him steady air, and striding
High there, how he rung upon the rein of a wimpling wing
In his ecstasy!”
—Gerard Manley Hopkins (1844–1889)
“Death and life were not
Till man made up the whole,
Made lock, stock and barrel
Out of his bitter soul,”
—William Butler Yeats (1865–1939)
