Try this, it has a lot of good info:

If you search the forum for ReDem you will find even more information.

This tutorial from bnsf subdivision was nearly the only one I found to work for me (new to route building/TS2013)

It's the mediafire download in the top post.

And remember to use decimal degrees for Lat&Lon.
ReDem is you friend and absolutely worth the $7 for the full version.
It takes some head scratching and re-reading at times, but it will work out.
Lots of knowledgable folks in this forum too.
