Abstract

For the planned Gotthard Base Tunnel the capacities of a number of variants have been determined with the aid of operational simulations. Decisive for the system choice was found to be the outlay for maintenance of the installation. Maintenance of a double-track tunnel is more expensive than for a single-track tunnel, for two reasons: Reduction in the work that can be performed owing to the traffic on the adjacent track, and the large number of track changes. Together with aspects of production, maintenance, safety, construction and ventilation/ cooling, the results of the capacity study enabled a decision to be made in favour of a system with two single-track tunnels. The Task In the autumn of 1992 the Swiss electorate voted in favour of two new railway routes through the Alps at the Gotthard and the Lotschberg. Since then
