Like most Underground lines, the Piccadilly line is operated by a single type of rolling stock.
In this case it is the 1973 tube stock.
The trains are painted in the standard London Underground livery of blue, white and red.
Seventy-six trains out of a fleet of 88 are needed to run the line's peak service.
One unit (166-566-366) was severely damaged by the terrorist attack of 7 July 2005.
The stock was recently refurbished, and was due for replacement by 2014, but the order for new trains was cancelled in July 2010.

The line was previously worked by 1959 stock, 1956 stock, 1938 stock, standard tube stock and 1906 gate stock.

The line has two depots, at Northfields and Cockfosters.
There are sidings at Oakwood, South Harrow, Arnos Grove, Rayners Lane, Down Street, Wood Green, Acton Town, Ruislip and Uxbridge.
