Lastly... omgosh I need to learn how to texture better!
The best piece of advice I can give you is start a new tile, and find a min of 3 grass textures that work well, at least one of them has to have good results at max scale, because this is going to be your base grass colour. Then find a few that match - or close enough to - the ballast, both only need to be at min scale. Save all these textures and order them with which you use first > last in the following steps:
Now paint the area with grass, large scale texture, HOLDING [ or ] keys the entire time, and with the smallest brush. This may take a long long time, but well worth the effort. Do the same with the ballast - lowest scale, except don't hold the mouse button, instead give it taps, because you don't want to ruin the detail of the texture.
Repeat with other ballast textures until you have a nice blend, try to avoid similar patterns appearing, as this is the whole reason we go through this long process. And again with the grass, only difference is that we are highlighting now, not covering. And play with the scale - always holding [ or ] for rotation. LOTS OF TAPPING.
A few key things that really make a world of difference is the obvious smaller details like; browner grainy textures beneath trees, this can give the effect of shadows and/or fallen leaves.
Just look at photos and see what little differences you can emulate with texture'ing. The main thing to pay attention to is that the colour of the ground in real life isn't that colour for no apparent reason, nature makes it that way for it to be an effective balance for our flora and founa. Trainz shouldn't disregard this. Don't paint random colours for no reason, every texture has to be able to tell a tale.
