the grader long blade & TIRES should possibly have been weathered more from use?
Excellent flat car and track ties & rails though, Well done! Bravo.Tr1 m.t.f.
The only thing I have done to new loads like this, is put some gray powder down an a paper towel, rolled the wheels over a piece of packing tape with the sticky side up and then over the powder to adhere some to the treads. Makes it look like it's been driven out onto a concrete apron in readiness to be loaded.
