A seven-car train of 1996 Tube Stock at Stratford on 18 January
2006 showing the “seven-car” sticker to the right of the car
number, hastily applied to all such trains after the incident on 22
December 2005, when a seven-car train slipped into service before
the commissioning of such equipment.
The Jubilee Line fleet was enhanced to 63 trains during March
2006 by the entry into service of the four additional new trains.
