Title

Cogitare have successfully reduced the forecast energy consumption of several London Underground Line Upgrades by approximately 20% and reduced whole costs by about £200m per line whilst maintaining or improving performance. How?

Cogitare was appointed by London Underground to identify how the private partner plans for implementing new enhanced rolling stock and signalling could be optimised to improve performance and reduce energy and costs. We developed a modelling and simulation process to model the combined whole life costs and benefits of alternative train system options. :

The project involved:

• Facilitating joint technical working groups between London Underground and the private partners (Metronet/ Tube Lines) to identify feasible options.
• Modelling the financial impacts of options on London Underground and the private partners
• Optimising options with results of business case analysis
• consultation and involvement of stake-holders enabled buy-in to the optimised solution.
• Project management of Conceptual design
• Project initiation and implementation. We developed the project and obtained funding approval where required to the point at which the project was handed over to internal departments to implement.

By identifying and implementing optimised solutions Cogitare reduces London Underground costs and simultaneously improves private partner profits.
