Developer Veridon has signed a deal with Canadian Pension Fund giant HOOPP to finance the major intermodal rail freight project at Rossington.
The inland port, known as iPort, is being built to ease pressure for storage at major coastal ports.
Despite being more than 40 miles from the coast, the rail freight interchange will have customs facilities and bonded warehouses on site, meaning it is officially classified as a port.
Goods will mostly come from Felixstowe in Suffolk and will be freighted to the warehousing complex.
As well as financing, the project hinged on the Finningley and Rossington Regeneration Route Scheme (FARRRS), which will connect the rail freight terminal to the motorway network.
Carillion starts this element of the massive redevelopment scheme under a £56m contract this month.
The local construction boom in the area will also be fuelled by Harworth Estates’ plans to redevelop the nearby Rossington Collliery site with 1,200 homes
