Found why that wasn't happening as I had the 2 images of the belt in the wrong places in sprite.Would it be possible to build conveyor belts on slopes next to the ore crane? See picture below.
If the image can explain it. The top 2 are how I had them in the sprite.
When they should have been the other way around like the bottm too.
With Railway stations and platforms .. the one on left should always be facing a SW to NE direction and the other NW to SE.
Found a few others I have wrong as well.
If you open the Rail Station Selection and click on the top Coal Loader sidings End, Normal.
You can see the left side track travels South West - North East Direction and the right side one North West to South East.
Well all the other pieces in that menu should all be facing the same. But I notice there are several that are wrong.
Pieces facing South-West to North East will only go on slopes the same and will not go on a slope the other direction.
I'll put my Car parks on hold for a day and see if I can fix these errors in the Mining Industry.
Until you told me about the problem, I would not have realised of my mistakes .. much appreciated as you help me learn something new.
