Hi hornbytrain,
World origin is the location of the route in latitude and longditude. In other words the position on earth. When set right it makes the sun appear in the right place for sunrise and sunset, which in turn make the shadows appear on the proper side of buildings and rollingstock. Can affect the time of sunrise and sunset, but does not do much other than that.
Cheers,

No not really. Those are fixed in the game regardless of season.
The real potential use for the world origin is if you are working from a map from which you can obtain the latitude and longitude of multiple points of interest, such as Google Earth. You can determine the exact position of a point, say the start of the tracks you wish to model, and then set your world origin there and write in the proper latitude and longitude numbers. You can then place multiple "trig stations" (found in the objects menu) at points useful to you in laying additional track or in placing objects and they will give you a read-out of the latitude and longitude at that point. Move them around and the numbers will change.
I've never used them this way my self, but I think some people have done it. It is all discussed in the manual.
Does this mean that with this, a route that was accidentally built upside down (N becomes S, E becomes W kind of thing) can be corrected just by adding a world origin and fiddling with the values?
Cheerio,
Nicholas.

As to correcting routes that are built upside down...ALWAYS check the minimap compass, and orient North, Up...once you create a route 90 degrees, or 180 degrees off...you will never do it again...it cannot be corrected.
I have no idea what the Auran "birdbath" World Origin compass really does.

Interesting question, never thought of that but I have used the wrong figures before :hehe:
I would imagine so, but you may need to convert your figures. If on your layout you can pin point a place and then get the Lat/Long reading for that point, you could do this.
I use these figures all the time and if you gave me an example and told me where you got it from , then I hopefully can explain how to convert the figures to something the World Origin Marker understands.
Without an example, it is not that easy to explain.

I had long wondered about this. When I made the map "NYOW Cadosia TRS2004", I followed the map in Carsten's book "NYO&W: The Final Years". Unfortunately, someone at Carsten's located their map compass upside-down, so my layout is oriented as such. At this present time, I have little time to fix it by re-making it and have subsequently stopped all map-making by their maps as a result (I was nearly done with Middletown, NY).
When I started a map based on the Visalia Electric (from the article in Model Railroad Planning), I mis-understood the map and made a similar error. I'd rather not re-do it, even though it's only 1 baseboard.

The World Origin itself is no more than a reference point, mapping an arbitrary point on some baseboard in Trainz Cartesian coordinates to geographic coordinates (i.e. latitude and longitude). This is called a "false origin" in cartography. As it is only a single point, it will not influence north orientation or scale.
Internally the World Origin seems to be used for calculating celestial math, the "orbits" of sun and moon.
There is also some inherent map projection in Trainz associated with the World Origin. A map projection converts the curved surface of Mother Earth to a flat plane, like a Trainz route. However, in this case, we do not know which of the many existing projections is implemented. It seems to be rather basic, anyway. I can only discourage people from using it for actual georeferencing. Compared to a proper and accurate projection used in cartography like UTM the one in Trainz has systematic and non-linear error, which is also different for longitudes and latitudes.
