The journey from Interlaken Ost station up to the Jungfraujoch, the highest rail station in Europe, is an amazing feat of engineering. The last part of the ride up is inside a huge tunnel carved out of the mountains at the turn of the last century. The journey starts at the Interlaken Ost station where you catch the BOB train up to Lauterbrunnen. Transfer there to the WAB train that climbs up to the junction at Kleine Scheidegg after passing through the car free mountain village of Wengen. From Kleine Scheidegg you take the last leg of your journey on the Jungfraubahn train through the great tunnel to the top. From the top (over 13,000 ft) you can see for miles in all directions. Views are great of the largest glacier in Europe, the ice palace carved out of the glacier, the resturants inside and the overall experience.
