In 2006 Australia bought 60 refurbished Abrams
They were unloaded in Melbourne and then were to be rail freighted up to Darwin (North of Australia and about 5000km distance, its where most active defence bases are now)....
Unfortunately the weight of the tanks on the rail increased the loads to where they were over the bridge weight limits for rail up to Darwin. NO RAIL FOR YOU!
So rail was out and they were trucked up instead
