I love Swiss railroads. Would absolutely love to work there in the snow. Hopefully one day maybe... crossing fingers

Now the SBB won't be ordering new tilting trains it has come up with a plan to use the new Double Deck IC trains that will come into service in 2014 to Stuttgart and München.
http://www.tagblatt.ch/nachrichten/p...120101,2837804

For the trains to München the plan is to extend the hourly service from Geneva to St. Gallen every other hour to München. This is only possible from 2016, but only if the electrification works are completed by then and if the trains with the new bogies with "Wankkompensation" are approved in Germany.

What is "wankkompensation"? Does it has to do with cant deficiency?

It's basically a tilting mechanism.

This is what Bombardier has to say about it:

"This innovative system ensures the compensation of a carbody’s natural roll movement, integrated into the existing secondary suspension."

"Reduced mechanical complexity: a reduced mechanical complexity is achieved by the mechatronic multifunctional setup of the system, which allows for a compact design with short wheel base, even with integrated drive system. The system cinematic provides fail-safe behavior and allows for a wide carbody design with a first class space comfort even for double deck coaches."
http://www.bombardier.com/en/transpo...nic-technology

The system compensates the centrifugal forces that pull the car body out in a turn.

Its basically tilt compensation. When high train carriages, like double deck coaches, go through a curve they will tend to lean outwards. This limits the permitted speed in curves as you cannot allow trains to get out of profile.
The "Wankkompensator" is basically a sort of active suspension that counteracts this, and makes sure that the train stay perfectly upright, even in curves. That allows for a gain in speed. SBB wants to cut of 6 minutes of Bern - Lausanne so that Lausanne can become a system hub too. That and other speed gains will mean that from about 2016 onwards Eastern Switzerland will be half an hour closer to Western Switzerland.

Cool engineering system.

The part about the schedule is hideous, though, as always: such a project is justifiable irrespective of the situation in Lausanne, Bern, Chur, Skt. Moritz or St. Gallen.

What is your problem? You are against a company trying to maximize its profits by offering the most value to its customers it can?

I am totally anti-monopolist except on very core state functions, transportation is not one of them,

This has nothing to do with that. You just seem to forget that that you are pro market and pro properly run enterprises when the result doesn't fit your agenda.

SBB does not have a monopoly in transportation, far from that. It just tries to do as well as it can, and is succeeding.

Oberalp route (again). In the last photo the road is somewhere under the snow to the right of the railway. My car train was empty, with only 3 cars and 6 passengers. There are four car trains per day per direction, plus a regional train every hour.

Is that a typical winter's snowfall depicted or is it more than usual?

Currently we are seeing a lot more snow than usual in the mountains. There are places that have already seen more than 3m this winter.
One problem facing transportation in the mountains is that the winter has (until this week) been quite mild, but very "wet". So lots of snow, but because of the mild temperatures the snow has not frozen to the ground beneath it, and so moves quite easily. So there are lots of avalanches.

so where should it be implemented? Interlaken-Montreux?

Yes. The previous idea of laying a third rail between Zweisimmen and Interlaken (so to have a double gauge line) has been abandoned. It is hoped to extend the service to Lucerne, but to do that the problem of the rack sections must be solved. But I doubt this will happen.

Yes. See here.

I wonder if this system could also for example be used for services directly from Zürich airport to st. Moritz.
