Originally privately owned wagons were conveyed by trains regardless of design, construction or maintenance. A very serious accident in 1885 caused by a broken axle on a privately owned coal wagon, led to the railway companies and Board of Trade introducing a standardised inspection system. In 1887 a standard specification for the design and construction of goods wagons was produced.

It conforms in most respects to the standard specification, however the original owner is not yet known. It is of such modern design that it would have been permitted to run in fast goods trains at average speeds of up to 35 mph!.

It was kindly donated by Castle Cement from their Pitstone Works in 1991. It has "Petroleum Product" painted on the sides.
