MUMBAI: Three persons died in India's commercial capital of Mumbai, after falling off from the city's crowded suburban trains, which have been suffering from a traffic crisis, following an accidental short circuit of its signaling mechanism. Of the three deceased, two victims slammed into signal poles – which are erected alongside railway tracks – before falling off the moving trains. Several unconfirmed reports of seven similar incidents were also reported at several stations along the suburban railway's central line at Ghatkopar and Vikroli railway stations. A sudden fire at the Mumbai railway's signaling cabins in Kurla and Vidyavihar railway stations on Wednesday has thrown the entire signaling mechanism awry, forcing the railway operations division to switch from automatic signaling to manual signaling, which has considerably affected the railway traffic efficiency. The suburban trains ferries Mumbai's formidable workforce of over six million every day and peak hours sees the electricity-fed trains packed like sardines. Slower trains have only made more severe the human to space ratio in the train's already overcrowded compartments, with office going commuters keen on getting to and from work in reasonable time. The Central line of the Mumbai railway is one of the most used modes of transport and connects the business hub of south Mumbai to suburbs nearly 75 kilometers down-line to places like Thane and Kalyan. It should be mentioned that overcrowding and train related accidents result in nearly 3000 deaths annually along the Mumbai railway track!
