People travelling between Avondale and Morningside were forced to instead take the 22 bus route or jump in taxis that provided a shuttle service between the two stations.
UPDATE - 8:30AM: Clearance has been received for the trains to operate over the bridge, at a reduced speed. Services will now run the length of the Western Line. Please expect some delays while recovery is in progress. https://t.co/TzqkTvGfWE
