London Bridge passengers using escalator on the Jubilee Line Extension, the newest part of London Underground's Tube network
An escalator is a mass transportation device that moves passengers quickly and efficiently up or down between the floors of a structure. In reality, it is a simple moving conveyor but, instead of a belt, it has a series of ingenious steps that are self-levelling, driven by a powerful electric motor and chain system. This is combined with a moving handrail that moves at the same speed as the steps to provide passengers with stability. The really clever thing is that an escalator can never break down, it can only become stairs. The Jubilee Line covers ( miles) and serves 27 stations between Stanmore and Stratford. The equivalent statistic for the new extended section is 16km (10 miles) of which km ( miles) is in tunnel and km ( miles) on the surface. Work started on the £ billion project to extend the Jubilee line in December 1993. The extension runs from Green Park to Stratford and was opened in three phases during 1999.
