In 1998 CTL was approached by London Underground to assist in re-drawing all of their existing archived information (which pre-dated WWII) for the passenger escalators into an assembly plan which could be easily followed by their own installation team.
With help from Canary Wharf Drawing Office in London, CTL brought the drawing information prior to manufacture up to modern day standards and then manufactured the main drive shaft and idler. After completing full alignment inspection, both assemblies were stripped down ready to be delivered to the relevant stations for re-assembly.
This new approach enabled LU to install the escalator assembly in just a few days instead of around 3/4 weeks.
CTL has manufactured over 50 Top & Bottom Drive Shaft Systems to date (which incidentally provides the motion to drive the escalator steps) covering over 30 stations for Metronet and Tubelines.
