In December 1854, the "International Commission" had to meet again to redefine the structure of the "Railway track of Central Italy" that risked not being able to finish the work undertaken.
Under pressure from the Austrian Government, the Duke of Galliera became interested in entering the affair and also Paulin Talabot who was closely connected to the Parisian Rothschild house.
On 14 March 1856 a new agreement was signed in Vienna with which the Austrian government transferred its Lombardo - Veneto lines to the private company that had been set up with the participation of the aforementioned subjects.
The company was formed with finance from the Rothschild houses in Vienna, Paris and London and the participation of Italian financiers including Pietro Bastogi and the Dukes Lodovico Melzi and Raffaele de Ferrari.
On 24 May 1856, the concession already granted (16 June 1851) to the Società Anonima per la Strada Ferrata dell'Italia Centrale regarding the Pistoia - Bologna line passed to the new company.
