It was reasonably profitable, paying dividends from 1789, and with the coming of the railways, some of the proprietors formed a railway company. It became part of the Manchester, Sheffield and Lincolnshire Railway company, and although there were intermittent plans to convert parts of it to a railway, it continued to thrive as a canal. In 1907, subsidence from local coal mines caused the collapse of the Norwood Tunnel, and the canal was effectively split in two. Subsequently, the main use of the Chesterfield end was the supply of water to the iron industry, while commercial carrying continued on the Worksop to West Stockwith section until the late 1950s.
