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:
“It is only when we are very happy that we can bear to gaze merrily upon the vast and limitless expanse of water, rolling on and on with such persistent, irritating monotony, to the accompaniment of our thoughts, whether grave or gay. When they are gay, the waves echo their gaiety; but when they are sad, then every breaker, as it rolls, seems to bring additional sadness, and to speak to us of hopelessness and of the pettiness of all our joys.”
—Emmuska, Baroness Orczy (1865–1947)
“I met a Californian who would
Talk California—a state so blessed
He said, in climate, none had ever died there
A natural death, and Vigilance Committees
Had had to organize to stock the graveyards
And vindicate the state’s humanity.”
—Robert Frost (1874–1963)
