Track building guides?
Do you know any possible ways to have some kind of "guide mark" on the point where track should go? This would help track building very greatly as you could actually see where you want to go next.
I know exact wgs-84 coordinates of points where turnouts are, slopes and curves start and also the height of the point (in meters over sea-level).

AFAIK, Oliver has written some basic tutorials for the initial steps with TransDEM, and I have also scribbled something for this "series". Possibly this could help, but I'm not sure.
Do you have some sort of map or just singular coordinates? You could enter these coordinates as control points in TransDEM and draw lines between them. In order to do this you either need a bitmap map suitable for georeferencing or a DEM - SRTM will do.

As everybody is mentioning me ...
I've written some very basic tutorials for the first approaches of track building in britain. They are far from beeing complete and - as it looks like - still not exact enough to help non german speakers to use the tools.
If anyone insists on having them I'll upload them on my website.

A somewhat unconventional approach but could work - the basic steps:
Create one or more xyz files from your Excel sheet. xyz files are text files, each xyz group is one line. x is long, y is lat and z is elevation. Lat and long format should be decimal degrees, elevation in metres.
Download the SRTM DEM for your area. Open in TransDEM and crop to the region you need. You need a DEM as the footing for all further work with TransDEM.
Open an xyz file in TransDEM. Each xyz file will produce one polyline. Do the polylines resemble anything close to a railway line? If yes, then this will be your raw route.
