The transport of crude
The fourfold increase in production of crude that accompanied the discovery of flowing wells during 1861 and 1862 exerted a critical pressure to improve transport facilities and better methods of handling and storing oil. By the late 1860's response to these pressures brought about the adoption of two major innovations affecting the future transport and handling of petroleum: railroad tank cars and gathering pipelines. By this time also the Region was threaded with local railroad lines which, through their connections with the major trunk lines, offered ready access to major marketing areas. But to meet the immediate necessity of getting their oil to market during the intervening years, oilmen turned to the more promising all-water route down Oil Creek and on to Pittsburgh via the Allegheny River.
