I costi della trasversale ferroviaria del San Gottardo sono stati rivisti al ribasso e la spesa finale potrebbe risultare di 18,5 miliardi, ossia 185 milioni in meno rispetto al preventivo.
Come emerge poi dal rapporto dell'Ufficio federale dei trasporti, che illustra lo stato dei lavori a fine 2013, le scadenze per la messa in servizio non sono cambiate: galleria di base sotto il massiccio dal dicembre 2016 e Monte Ceneri due anni dopo.
Procedono secondo programma anche i lavori per i raccordi alla rete europea ad alta velocità nella Svizzera orientale e in quella occidentale.
