Your freight house / team track / transfer crane would not be complete without a loading dock. Maybe cover it partly with a roof (no walls), depending on climate.
Depending on volume put out by the mines, either direct transfer of ore or a stamp mill to reduce the volume?
Beer and whisky distributors.
Private teamtracks? More than one of everything if you have room for it.
Transloading of stone (ballast / limestone)
Your choice: narrow and standard gauge track on one side of the freight house etc. or each on a separate side.
