Hi All,
When placing a "Ore Dock Loader" on ground and adding "Iron ore Dock All Up " to the unit, Can you place these units together and how do you do itHCheers, Robynneave heard that, leave a gap between the two units and add track
but hard enough to get units level on top let alone join both together.If someone can help ,many thanks for the help..Cheers,Robynne
