Yes, I have in fact been working on it.
Here is what I have so far for TTD-Scale...
1
The example tracktype from the NML example file.
2
Transport Tycoon Deluxe for Comparison.
3
Current state of TTD-Scale.
It is currently unshaded, due to me not knowing how. It will be shaded, but as the toy-like appearance used in TTD is hard to imitate without breaking copyrights, I'm trying to use very little shading to compensate.
Question to go with it, do tracktypes require ballast in the graphics (as seen with glitches in NRT)? If so, an OpenGFX with grass tiles in place of rail tiles could be a good non-coding solution.
