Train services across various regions are facing significant disruptions due to engineering works and technical failures. In Visakhapatnam, several trains, including the Gandhidham-Puri Express, are being cancelled or diverted to facilitate safety-related modernisation works and the commissioning of a third railway line. Meanwhile, in Hereford, a points failure is causing delays and cancellations on routes including Worcester Shrub Hill, with disruptions expected until 4 PM. In London, extensive engineering work is affecting services between Blackheath and Charlton until August 11, with alternative routes provided for passengers. Additionally, damage to overhead powerlines near Stockport has resulted in cancellations and diversions on the West Coast mainline, prompting passengers to check for updates from their train operators. Authorities are advising all affected passengers to plan their journeys carefully and utilize alternative transport options where necessary.
