1995 Stock History
In the early 1990s, London Underground concluded that the existing 1959/1962/1972 stock in operation on the Northern Line had reached the end of its serviceable life. Following the tendering process, the contract to build the replacement trains was awarded to GEC Alsthom, who began construction of the new trains in 1996, although the bodyshells were actually manufactured in Spain and transported to the UK.
The first of 106 trains was delivered from Washwood Heath to Ruislip depot on 20th December 1996, with unit testing being commenced in January 1997. Following the extensive testing program, the first train entered revenue service on 12 June 1998 and with steady deliveries of the new trains, the final unit entered service on 10th April 2001.
The 1995 stock bears a striking resemblance to its sister 1996 stock and this is indeed because they have the same bodyshell design. This however is where any similarity ends, as there are major mechanical and electrical differences between the two stock types.
The major mechanical differences between the two include their traction motors and bogies, with interior differences including the use of tip-up seats on the 1995 stock (1996 stock has perch seats), Orange LED matrix screens rather than Red and the use of selective door operation, the only deep-level tube stock to feature this, due to several short platforms along the line.
Fifteen years after their entry into service, the 1995 stock entered a refurbishment program beginning in 2013. This refurbishment by Alstom saw the floors of the cars replaced, repainting of the grab rails, replacement of the seating moquette and removal of bother the internal and external door control buttons.
The exterior of each train also benefitted from polishing the windows to remove graffiti and having their corporate livery reapplied. The first refurbished unit re-entered service on 30 May 2013, with the last returning to service in April 2015.
