Help! Can anyone out there give me some advice on how to configure a LARS unloader for minerals please? I've created a quarry where I can load minerals (eg sand or ballast etc)and I want to deliver it to a wharf and unload it, but so far I can't get any of my minerals hoppers to do it. They load without any problems at the quarry but when the train arrives at the wharf, nothing happens. I'm using a LARS generic unloader but I have no idea how to configure it. Would appreciate any help you can give.
