How much did the extension of Barcelona — Sabadell tunnel cost?

The Barcelona-Vallès S2 railway extension through Sabadell added 4.4 km of new line, four new stations and a rebuilt Can Feu-Gràcia station; the wider works covered 5.2 km and included a northern depot. The main construction contract started in March 2008. Two stations entered service in 2016, and the final three opened in July 2017. A Generalitat ex-post report lists €430 million as the investment associated with the completed extension in its overall inventory, while its detailed project analysis reports €334 million in liquidated investment costs. The report does not reconcile those two totals, so they are presented as different reported measures rather than a single unqualified final price.
