At last! Rivets!

Attercliffe Railway Bridge, built in 1864 for the Manchester, Sheffield and Lincolnshire Railway which owned the canal company from its establishment in 1847. The MSLR was formed by the amalgamation of the Sheffield, Ashton-under-Lyne and Manchester Railway, the Great Grimsby and Sheffield Junction Railway, and the Sheffield and Lincolnshire Junction Railway.

Until 1927 there was a station at Attercliffe, not to be confused with that at Attercliffe Road, which was on the Midland Railway line (Sheffield's one remaining station now being the Midland Station, whereas trains through Attercliffe ran into Sheffield's Victoria Station, closed in 1970, which gave the nearby Basin its new name.) Traces of Attercliffe Station can apparently be seen from the canal, but I shall have to look for them another time.
