Jubilee Line

Question

To ask Her Majesty’s Government what was the original estimate of the benefit-cost ratio of the Jubilee Line extension project when it was extended to the docklands.

Answer

The original estimate of the benefit-cost ratio of the Jubilee Line extension in 1991 was 0.95. This estimate was made before the scheme opened in 1999.

Subsequently a report by Colin Buchanan and Partners "Reappraisal of the Jubilee Line Extension", commissioned by Transport for London and completed in 2004, included a cost benefit reappraisal which calculated the benefit-cost ratio to be 1.75 using actual costs and the scheme’s contribution to increasing the country’s Gross Domestic Product.　This is the latest known benefit-cost ratio estimate for the extension.
