Strange request. We would like to visit Mt. Titles. We want to take the Zentralbahn railway direct from Lucerne to Engelberg. The issue is my wife is claustrophobic and has issues with tunnels. If she is aware of the tunnel before we go through it and approximately how long (distance and time) it takes to travel, it greatly helps. Has anyone any first hand experience with this route? Is there any other option? On another day we will be going to Mt. Rigi by boat. No problem there. Thank you in advance.
Zero tunnels on that route.
I think you already asked about this. There is a tunnel.
