The UK DfT threw out its own West Coast rail franchise award over flawed bid math

In August 2012 the Department for Transport announced FirstGroup had won the InterCity West Coast franchise, replacing Virgin Trains on the London-Glasgow route from December. Virgin Rail Group, whose bid it had scored below First's, refused to accept and filed for judicial review, saying civil servants had 'got their maths wrong'.

As officials prepared the government's court defence, they discovered the department's own evaluation was broken. On 3 October 2012, new Transport Secretary Patrick McLoughlin cancelled the competition, citing 'significant technical flaws': mistakes in how inflation and passenger numbers were factored in, and in how much money each bidder was then asked to guarantee. The DfT said it could not be confident the errors had not changed the result, stopped contesting Virgin's case, suspended three officials and paused the Great Western, Essex Thameside and Thameslink competitions.

The scale was stark. First's winning bid carried a net present value in the billions with a £50 million subordinated loan facility; Virgin's bid, worth £5.3 billion, had none. Laidlaw's inquiry found risk adjustments of £70-160 million were being weighed against FirstGroup's roughly 5% operating margin, produced through 'an accumulation of significant errors' with inadequate quality assurance at every level.

Richard Branson called the episode a 'fiasco'. An inquiry led by Centrica chief executive Sam Laidlaw reported in December 2012, finding the DfT primarily responsible; a second review by Eurostar chairman Richard Brown followed in January 2013.

DfT had to reimburse all four bidders' bid costs, suspend three officials, pause three other live franchise sales, and rerun the competition for a route worth billions.

The evaluation model mixed bids built on different assumptions and then risk-adjusted them with a model nobody had validated against reality.

The flaws surfaced through litigation discovery, not through the department's own quality assurance, which the Laidlaw inquiry found inadequate at working level and management level.

Risk adjustments of £70-160 million against a bidder's roughly 5% margin were so large they should have triggered a sanity check before award.

The department kept multiple franchise competitions running in parallel on the same flawed machinery, so one failure froze the whole programme.

Officials defended the award in public while the underlying model could not have survived basic testing.

A model that decides a multi-billion-pound award needs its own stress test. When risk adjustments swing £70-160M against a 5% margin, ask what the model measures before signing.

Virgin kept running West Coast under temporary and then extended contracts for seven more years. The franchising programme was rebuilt around the two reviews' recommendations and relaunched. In 2019 the route was awarded to First Trenitalia, a FirstGroup partnership with the Italian state operator, after Virgin was barred from bidding; Virgin's branded service ended that December.
