During my trip to Switzerland, I was really excited to travel in this train journey. I booked a Swiss travel pass which cost me around 180 Euros and covered all trains inside Switzerland including this one. If you are travelling with Euro rail pass then this train is not free for you. Also seat reservation are compulsory for this train. All the catering services are present inside this train, and you can book a buffet for you inside. The train is a panoramic journey and I felt that I am almost flying through these beautiful mountains.
