Problem: The coal dumper industry has a collisions problem meaning none of my rollingstock, let alone my hopper cars can get in, plus the button that (presumably) allows hopper cars to enter the dumper for spin-dumping doesn't work. Please fix this, this is making coal industry and haulage RP very difficult.

I could however suggest an animated coal loading (just dark particles is enough) at the mines, though that is just a suggestion besides the point.
Thank you.
