The Piccadilly line is a line of the London Underground. It is coloured dark blue on the Tube map. It is the fifth busiest line on the Underground network judged by the number of passengers transported per year. It is mainly a deep-level line, running from the north to the west of London via Zone 1. However, there are a number of surface sections mostly in its westernmost parts. Out of the 53 stations served, 25 are underground. It is the second longest line on the system, after the Central Line.

Infrastructure

Rolling stock

Piccadilly line trains of 1973 stock at Rayners Lane station

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,[2] but the order for new trains was cancelled in July 2010.[3]

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 Northfields55 map 55 and Cockfosters.54 map 54 There are sidings at Oakwood, South Harrow, Arnos Grove, Rayners Lane, Down Street, Wood Green, Acton Town, Ruislip and Uxbridge.

Signalling

The line is controlled from the control centre at Earl's Court, which it used to share with the District line. It is in need of resignalling, and this work is planned to be carried out by 2014.

Service pattern

The current off-peak service pattern is:

6 trains per hour Cockfosters – Heathrow Terminal 5 (via Terminals 1, 2, 3)
6 trains per hour Cockfosters – Heathrow Terminal 4 (returning around the loop and serving Terminals 1, 2, 3)
3 trains per hour Cockfosters – Uxbridge
3 trains per hour Cockfosters – Rayners Lane
6 trains per hour Arnos Grove – Northfields

Often late evening services terminate at Oakwood instead of Cockfosters.

Trains will also make an additional stop at Turnham Green during early mornings and late evenings but will not stop at the station during the main part of the day.

Other services operate at times, especially at the start and towards the end of the traffic day.
