To gpz: as far as I know only last generation tilting trains have countertilting mechanisms for pantos. The catenary is already laid down so as to consider panto displacement due to curve superelevation, so such mechanisms are not needed.
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...

I'm just talking about the results in OR, at full tilt in a tunnel the train hit the tunnel wall. :oldstry:

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.

Interesting! All commercial production for years later (ETR 450, ETR 460-465-470-485, Virgin Pendolino, ICE-T) hadn't this mechanism. Only in the last years they are using it again.

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.

To the ORTS development team: A big thanks and congratulations on making this feature for the simulator. It is just amazing to see the train through the superelevated curves. Sure gives a great look specially when taking screenshots of trains taking the curves!
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. ;)

Thanks Jefe, yes, it's true, I too have signaled to the ORTS team that trainsets with two axles and less do not inclinate in curves.

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.

I was just wondering, on how does the simulator know if a car has two or more axles. I tried to make a little experiment with the "numwheels" parameter but no results with that. Passenger cars with bogies of 4 axles work fine even with "numwheels" at the value of 1. I was wondering of where does the simulator gets such a info, how can it distinguish the cars...

I'll have to look at some videos again to see how much 'super-elevation' applies to slog-speed narrow gauge.
