Bernd & Kai,

Wouldn't the following Module doing those calculations for us? Why do we need to do them manually? or one I am using currently)
If we are using above products do we still need to process the positioning information we have?

I'll go through Kalman filter as per your suggestion. Don't have any model of tracks.

Any specific books/web pages that provide these intricate details?

Yes, that is what I had in my mind, but since you get gyro +
accellerometer in one chip these days, I somehow started to call them
gyro only ;)

Gyro might still be interesting, though, if you want to measure steep
climbs or call the rescue if the locomotive is rotating in unexpected
