Talgo submitted the strongest technical bid, which is worth 35 points from an overall score of 100, while Renfe says CAF provided the best economic offer, which is worth 65 points.

Talgo, Alstom and Siemens submitted two offers each for differing train configurations, and each offer has been scored separately. Talgo’s offers scored 28.1 and 29.6 in the in the technical section of the bid, followed by Alstom (25.1 and 24.5), CAF (22.6), and Siemens (21.3 and 21.5).

For the initial tranche of 15 320km/h trains, CAF submitted a bid of €321.3m and €549.6m for 30 years' mainteance. Talgo is offering a price of €337.1/€337.5m (depending on the variant) with a €449m bid for the mainteance contract. 

CAF's train would seat 487 passengers, while both Talgo variants would seat 521. Talgo is pledging availability of 99.09% for both variants against 91.15% for the CAF train. 

At least 10 of the trains will be allocated to cross-border operation between France and Spain, and will therefore be equipped with three different electrification systems, and three different signalling systems (ETCS, TVM 430 and Asfa).

This is Renfe’s second attempt to find a supplier for its next-generation high-speed train. In May an administrative court ruled against Renfe and ordered the company to restart the procurement process after suppressing a clause that required bidders to manufacture most of the components for the trains in Spain.
