Aurizon in talks to sell $3.5bn stake in coal rail QUEENSLAND coal hauler and railway owner Aurizon Holdings has started talks to sell a stake of up to $3.5 billion in its existing coal railways as it restructures the company with a view to increasing growth funding options. The move, which sent Aurizon shares to a record high yesterday, comes as Aurizon talks with the companies of the nation's two richest miners, Gina Rinehart and Andrew Forrest, about taking stakes in railway infrastructure on both sides of the country.
