Construction has stopped on an interstate rail hub in southwest Sydney that is supposed to get freight off trucks on to trains after logistics group Qube scrapped a $140 million construction contract signed a year ago with Martinus Rail.

Qube, which has been building an interstate intermodal terminal at Moorebank after selling land and warehouses at the site to the Logos Property Group in a $1.65 billion deal, said the contract with privately owned Martinus was terminated on Monday night.
