The Eppenberg Tunnel is a railway tunnel in the Canton of Solothurn, Switzerland. It is part of the 'Future Development of Railway Infrastructure' plan (German: Zukünftige Entwicklung der Bahninfrastruktur or 'ZEB') and increases capacity on the Aarau–Olten line in the Schönenwerd–Däniken section. A particularly constraining bottleneck in the Swiss rail infrastructure is in the section between Aarau and Olten, which has only two tracks at Eppenberg-Wöschnau, Schönenwerd and Gretzenbach. The route has to be shared by international and national passenger trains as well as freight. Hence quadrupling the complete line between Aarau and Olten has high priority among infrastructure projects. The main purpose of the tunnel is to increase capacity. The two additional tracks in parallel with the existing double track line will effectively create a four track line. The Council of States adopted the law authoring the 'ZEB' programme in the spring session of 2009, authorising the budget for the Eppenberg tunnel. Due to the large financial requirements for the New Railway Link through the Alps project, construction of the Eppenberg tunnel only began in 2015.
