When the vessel arrived, they would be moved to the side of the ship along with other cargo to be lowered or carried into the hold and packed by dock workers. The ship might call at several other ports before off-loading a given consignment of cargo. Each port visit would delay the delivery of other cargo. Delivered cargo might then have been offloaded into another warehouse before being picked up and delivered to its destination. Multiple handling and delays made transport costly, time consuming and unreliable. Containerization has its origins in early coal mining regions in England beginning in the late 18th century. In 1766 James Brindley designed the box boat 'Starvationer' with 10 wooden containers, to transport coal from Worsley Delph (quarry) to Manchester by Bridgewater Canal. In 1795, Benjamin Outram opened the Little Eaton Gangway, upon which coal was carried in wagons built at his Butterley Ironwork. The horse-drawn wheeled wagons on the gangway took the form of containers, which, loaded with coal, could be transshipped from canal barges on the Derby Canal, which Outram had also promoted. By the 1830s, railroads on several continents were carrying containers that could be transferred to other modes of transport. The Liverpool and Manchester Railway in the United Kingdom was one of these. "Simple rectangular timber boxes, four to a wagon, they were used to convey coal from the Lancashire collieries to Liverpool, where they were transferred to horse-drawn carts by crane." Originally used for moving coal on and off barges, "loose boxes" were used to containerize coal from the late 1780s, at places like the Bridgewater Canal. By the 1840s, iron boxes were in use as well as wooden ones. The early 1900s saw the adoption of closed container boxes designed for movement between road and rail. On 17 May 1917, Benjamin Franklin Fitch inaugurated exploitation of an experimental installation for transfer of the containers called demountable bodies based on his own design in Cincinnati, Ohio in US. Later in 1919, his system was extended to over 200 containers serving 21 railway stations with 14 freight trucks. Prior to the Second World War, many European countries independently developed container systems. In 1919, Stanisław Rodowicz, an engineer, developed the first draft of the container system in Poland. In 1920, he built a prototype of the biaxial wagon. The Polish-Bolshevik War stopped development of the container system in Poland. The US Post Office contracted with the New York Central Railroad to move mail via containers in May 1921.
