Superelevation

I've tested today the latest version with this Superelevation, which is amazing really good job, but I have to report that all TGV family, AVE/Euromed and many EMU's which have Jakobs bogies doesn't elevate at all. Also the Talgo Trains from Renfe, which are specially made for tilting, they stay always at the same position.

Jefe del CTC: I'm not very sure to have understood your post. What do you mean by "elevate"? TGV families haven't any tilting mechanism at all.
To billpers: I have participated to the development of the first generation of Pendolinos and can tell you that they tilt in curves above a minimum speed and lateral acceleration and they don't bother at all if the curves are within tunnels or not. The transversal section of tilting trains is a bit smaller than that of conventional trains, so that they don't need broader cuved tunnels or to tilt less in such tunnels. Think of the risks if the section of tilting trains would be such that due to a tilting malfunction they would hit the tunnel walls at high speed...

The very first fiat pendolino already had this feature. There is a good image on the web showing the counter tilting on a testing unit.

A note about superelevation on tunnels: I asked experts here in my country and they wrote me that there aren't restrictions for superelevation on tunnels. Of course the tunnels must be of adequate section, and there is also a trick: in single-track curved tunnels the tunnel axis and the track axis do not coincide to take into account the superelevation effect. For example, in a left curve tunnel the tunnel axis is a bit at the left of the track axis, that is it has a bit smaller radius. So this compensates the additional space that the train needs to its left due to its bending.

I mean the behaviour on a bend in OpenRails. Shared bogie trains and all 2 axes freight cars doesn't superelevate aswell on the simulator..

Here are few examples.

My only "request" for now its to try to solve this problem with wagons with only 2 axle freight cars/passenger cars or even little diesel units, to make them also "tilt", as Jefe del CTC has pointed out.
Here's a screencapture I've made with a Czech train departing from a station that is built in curve. ;)

I have uploaded on Youtube a 4 minutes clip about tilting trains and superelevation on ORTS. About audio: I inserted my suggested paths for bug #1095066 in ORTS to get some audio effects that do not work with the standard ORTS version.
