<<" Singapore on 30 October 2016 and will reached Zurich Airport on 31 October 2016.">>
Good to hear that you will be there at the beginning of the month. Likely nicer weather. Could be still quite pleasant at lower altitudes. Of course "pleasant" is all relative, compared to the much higher average temperatures in Singapore. ;-)
Take multiple layers of clothing/sweaters with a windbreaker or light jacket, not heavy coats.
I like Wengen, and so does Kim. Here is a little light reading all about Wengen and the surrounding area:
A lot of what she discusses will not be open when you are there, but the guide may still be useful.
Unfortunately, the cableway from Wengen up to Männlichen will be running only until October 23rd, as will the alternate route from Grindelwald.
The cograil to Kleine Scheidegg and the Jungfraujoch runs all year.
The set of cableways to Schilthorn are closed for maintenance during part of November, starting on the 14th, but you could go up there while you are in Wengen. See screen grab, attached.
I have expanded one journey (by clicking on the plus sign to the left of the journey) so that you can see more details.
If i were doing it, I'd go to the Jungfrau region first, but any way will work and, as Arno noted, you absolutely must learn to use the timetable.
<<"Then we will take the Glacier Express from Matterhorn (free with Swiss Travel Pass) to another areas (hopefully not too far as daylight is short). We will then proceed to Bern from Zermatt, after 2 Night in Zermatt,">>
Use the timetable and the map that I linked you to to help decide where you want to go and see if the local trains/buses/cableways are running. Trains will run.
Zermatt is rather isolated, and not a good base for other travel. But, you might enjoy a short visit to Brig or a ride up to Kandersteg via the scenic line up the side of the Rhone Valley.
<<"to catch the Parliament house light show! (don't really know how much is the ticket) ">>
Neither do I, but I'd be surprised if it is not free. At least one link on the internet says that it is free. The tourist office in Bern main station or Wengen can guide you on that. I've not seen it, but it looks spectacular. Only on certain days:
<<"after 2 nights in Bern, we will go to Wengen(Jungfrau!!!!) for 4 nights before we return to Zurich on 8 November 2016 to go to Mt.Titlis at Lucerne! We are departing Switzerland on 11 November.">>
Here is a lot of information about Titlis. I think that the cableways to the top ( called Kleintitlis) may not be running while you are there, but you can certainly get partway up.
I'm not sure about which days the November maintenance period will occur.
Here is an interesting thread about a visit from Singapore by JaneQ, last December. it's a long thread; find the posts on Nov 3 at 7:29 PM ( and others) for some comments about Zürich:
Her report of her trip, even though it was not at your time of year, may be useful, too:
She enjoyed Schilthorn.
Coverage of rail passes-
Arno gave you a link. This one may also be useful:
Lake boats on all lakes are covered.
This is a long thread about a hike near Luzern, but partway down it are some pictures of the lake:
I've attached a couple more. The ones taken from Hammetschwand are from the top of a mountain ridge very close to Luzern, as shown in one of the photos.
