Grades incorrect in Tane

[LarryFord]

It appears to me that the grades when laying track are incorrect by a factor of 3.28084. That number happens to be how many feet are in a meter. It appears they are taking the horizontal distance and dividing by 3.28084 and then dividing that by the difference in elevation between spline points. An easy way to test this is to lay a section of track 100' long. Set the elevations at each end of the track so they are exactly 1.00 feet different. example 0.00 at one end and 1.00 at the other and then check to see what the grade is on this section of track. It should be a 1.00% grade but it reads 3.30% grade.

Height is always measured in metres in Trainz regardless of whether you have chosen imperial or metric units.

Gradients are a ratio, and are universal (the same) in Imperial & Metric

So when I type in an elevation using Imperial units, I am entering an elevation in meters?

Correct, if you set one end at zero you need to set the other end at 0.3937 to get a one foot elevation.

Keep in mind that Trainz has been made in Australia since the first version, and the standard unit of measurement in Australia is the metric system.

This is something I've always suspected because of grades not being prototypical on imported routes. On routes I've worked, and ended at elevation that I know are incorrect. Now I understand why.

Um.. there are 39.37 inches in a metre so your ratio is a bit out.

It should be 0.3048; ( the number of metres in a foot).

Sorry to be such a pedant...

The metric system is easy to use. I made up a chart:

It seems the magic number to divide by, is @ 3.28
Numbers rounded off to simplify things.

I was just made aware of this by a Trainz friend yesterday. Apparently it has been known by the community for a while, but I don't recall seeing it mentioned in the manuals. Is there any possibility that the developers will either (a) make a program change so that elevations are in English units if that is selected, or (b) at least add the fact that elevation is always in metric to the documentation?
