A modern, enclosed, automated dumper station controlled by one operator works both the twin rotary Dumper 31 and the single rotary Dumper 32. Coal car dumping is done by inversion without uncoupling the rolling stock. In 2008 one of the dumper barrels in Dumper 31 was replaced in a changeout that allows the twin dumper set to handle the shorter, lighter U.S.-style aluminum coal cars two at a time. Two, fully-automated train indexers position the coal cars for dumping.

• Dumper 31 – working in tandem, the two rotary dumper barrels can unload at a rate of 6,500 tonnes per hour. Both can handle aluminum coal cars, and one of the barrels can still dump Canadian-style steel coal cars which are longer and heavier, but gradually being phased out of service.
• Dumper 32 – a single rotary dumper capable of unloading at a rate of 4,000 tph and can dump both aluminum and steel coal cars.
