In 1897 the Midland railway company were looking to build a line from Heaton Mersey to Sheffield and the route would pass lower down the slope. Although the canal had given no problems in the 100 years it had been at this location the railway company were troubled. They believed the canal could burst it`s bank and wash the railway line away.
In 1903 the Midland and Great Central railway owners of the canal agreed to move about 328 yards of the canal to the south. This was so the canal would sit on more stable ground but I think looking at the site today the railway company were worrying about nothing.
