 Whether or not such structures were inspected is unknown; it seems not, as several more collapses occurred some years later, at the Inverythan crash and the Norwood Junction rail accident in 1891.Thereafter, the vast majority of cast-iron underbridges on the rail network were eventually replaced by wrought iron or steel structures, although some cast-iron underbridges remain today, i.e.Robert Stephenson's High Level Bridge in Newcastle.
