Which London Underground line primarily uses trains known as 1996 Stock?

The Jubilee line primarily uses trains known as 1996 Stock.

The 1996 Stock was built for the Jubilee line’s major eastward extension, which opened in stages between 1998 and 1999. The trains were designed for the line’s modernised infrastructure and operate as seven-car units.

The stock is visually associated with the Jubilee line because of its silver body, dark window band, and distinctive front-end design. It replaced older 1983 Stock trains that had been introduced when the Jubilee line opened in 1979.

The year in the name refers to the stock’s construction and introduction period rather than the opening year of the Jubilee line. The Jubilee line itself opened to passengers in 1979, a date distinct from the later eastward extension and the 1996 Stock trains.
