QR National
(ASX:QRN) says a combination of factors have impacted forecasts and has now revised full year underlying earnings in the range of $540 to $580 million.
In February the company had advised underlying earnings of $578 million.
The guidance has been impacted by ongoing industrial action at BHP Mitsubishi Alliance Queensland mines, wet weather leading to closures and lower customer demand for coal rail transport.
In the first half of the 2012 financial year, QR National posted a net profit of $189.3 million.
