Many open wagons would find their way into private ownership, with each company then commissioning one of the Big Four companies to move their wagons to their destination. These plank wagons are typical of the kind that could be seen making up a colourful patchwork behind one of the Big Four's freight engines.

These open wagons are fitted with NEM couplings and metal wheels, allowing them to roll freely and therefore allowing them to run in long rakes behind even small locomotives as may sometimes be tasked with hauling them. These wagons also have internal plank detailing, a load need not be fitted if you do not wish to add one.
