Bernina express is one of the best panaromic trains in Switzerland and making a trip on it was once in a lifetime kind of experience. The train starts in Chur and crosses the Swiss alps and finally even crosses the Swiss border :P last halt for the train is Tirano in Italy. Borders in Europe are quite porous now with border controls removed (much like Indo-Nepal border). One recommendation, on board this train don't keep glued to yous seats, the best spot on the train is the slide-down window (sadly for which there is no reservation) but the cool breeze you can feel with the window down is what will give you real alps experience. Also pics come better with nothing in between your camera and its view ;-) .
On it's path the train crosses 55 bridges and 100+ tunnels. On board the public announcement system also keeps describing each place of interest as you pass it.
By crossing into Italian border I added one more country to my visited list (though don't know if its really counted :P). On the way back we took St. Moritz route. St.Moritz is a popular vacation spot in Swiss alps but not for people like me, it's ONLY FOR RICH PEOPLE and by rich I mean REALLY RICH. Otherwise it's not too exciting to see 5* hotels with ferraris and bentleys parked outside them :D
Last when I visited st moritz in 2006 it was in summers and we all enjoyed the beautiful lake. This time there was no lake, it was all frozen the place gets a total different look during winters, personally I liked the summer visit to St. Moritz(pic below is at St. Moritz during summer of 2006).
Finally again all the way upto zurich and then olten. A day where i spent 12 hrs in train but experience,one of the best of my life! Huge recommendation for anyone travelling to Switzerland. If u have only 1 day go on this train, u will see the type of Swiss u always wanted to see.
Tips for people planning traveling on Bernina express:
(a)All your Eurail passes, Swiss rail passes are valid. You just need to pay reservation fees of Fr. 9.- per person.
(b)Tickets can be purchased online or from Swiss tourism sites
(c) From a tour manager on board i heard there is heavy rush during summers so make sure you make reservations well in advance during summers.
