Anyway, it is not the actual programming, but rather the idea and how to implement it that makes original and creative minds stand out. Programming is a skill that can be learned by anybody who is determined and committed.
Young people like you are not yet fixed by their roots and think 'out of the box' more freely.
You do read http://www.tssf.eu/ since it is in German and more focused on Germany and its neighbours?
I am reasonably fluent in German also, but have not posted there yet. It is where Norbert Rieger has his own thread on DB Tracks, MS Tiefbau in German.
Hopefully somebody will pick up on a .stf track profile for superelevated DB Tracks.
(for non-German speakers, Google Translate will provide you with a coarse translation.)

We´ll see, what time will tell - may skills have way to go, and OR too, sowhos knows? ;)
Nope, I actually don´t read much in german/austrian forums, ´cause my real "love" are the aerican RR things (might also be a bit about bigger, stroger, heavier :D ) - That´s also why I hang out at Elvas: You get to talk to people who can help you, and also know about the real american things, which i just know from my PC :/

Algorithm: One of the formulas my engineering class was given for a superelevation transition from tangent to curve is L = 150*D*e, where D is the distance from the centerline to the lane edge. In ORTS, D would be the distance from the center line of the track to 1/2 the gauge, and E would be the percent-grade of superelevation - (Level/Grade).
Assuming these variables aren't in use, this could be how transition length is computed.
SPElevation = [Super Elevation Level]/[Gauge]
SPDistance = [Gauge]/ 2
SPTransition = 150 * SPD * SPE
2/3ds Rule: This specifies that 2/3rds of the superelevation must occur on the tangent preceding the curve, and the remaining 1/3 will occur on the subsequent curve. Of course, a whole wealth of issues are introduced in this. It would mean the Superelevation script would need to have a 6m tangent preceding the curve at its lowest setting and 9.5m at the highest setting, or to parse the preceding x meters of track and and apply the transformation.
Placement could be done by detecting the difference between "profiled" track and tangent track, and profiling the preceding / following SPT * (2 / 3) meters. If that distance is on a curve it could sum the transition in degrees into the other curve, but I'm not sure what kind of issues that'd introduce.

i.e. ===straight===,9,8,7,6,5,5,5,5,5,6,7,8,9,===straight===.
Would such an algorithm handle the multiple sections?

I use something similar, the issue is such a system doesn't exist outside ScaleRail unless someone generates...say...USTracks analogues to all the ScaleRail shapes. According to Tim Booth's rules that would require a Dynatrax license though. Then of course most routes using the Kuju profile do not have this either.

sir, sorry to bother you, I was informed from the open Rails page to contact you to ask how to put the cant on the 1000mm superelevation, look in the forum, but the links I found were down .. I hope you can help, Regards.

Hello, the translator I use is capable, but for the superelevation to work on the metric gauge 1000mm, which is exactly what I have to download? I hope your help!
