Painting is a bit hit and miss, and you may need to use combinations of textures to do what you want. However, it helps if you at least have an additional copy of the default textures listed in the Texturing.xml to help blend certain areas.
By extra copy, I mean that the route uses certain basic textures for ground, peaks, rocks, etc., and adding an additional entry in the Texturing.xml of these textures allows you to use them without destroying other paintwork, as fault textures will usually cut through custom terrain painting, and are near impossible to blend. Simply add a tag to the default entries as "Default", so as not to confuse those with the other textures.
Brush size, falloff, and strength need to be tinkered with to achieve the desired results (normally these can be left at default). For most everything, I use a falloff of 1.0, and a strength of 0.2. Brush size is whatever you're happy with, but I typically use a round size of 20 for single track, 30 for double, and 36 or wider for roads. You can usually layer 3 or 4 textures with good results, but be mindful that the first texture might get cut out with subsequent brush strokes.
BTW, this really should have been posted in the Route Design forum, as it's likely you're not the only one to run into this issue.
