Harbour Line services in Mumbai were hit on Wednesday after an empty local train derailed while entering platform 2 at CSMT during a trial run. Central Railway then redirected harbour line trains to platform 3 at CSMT, which is typically reserved for mainline services. The coaches were re-railed at 6.20pm, and scheduled train services resumed by 6.45pm. Commuters expressed frustration over the timing of the trial run, stating that it could have been conducted during less busy hours. Many passengers had to find alternative modes of transport to reach their destinations. Some were stranded in trains and had to walk in the sweltering heat to catch mainline trains. The incident caused disruptions and inconvenience to commuters.
