मुंबई कॉटन ग्रीन Mumbai Cotton Green (CTGN): Mercury levels in the city have reached a boiling point, so much so, that a railway track near Cotton Green station was found to have bent due to excessive heat on Wednesday. The incident led to a disruption of services between 2.20 pm to 3.25 pm.
The irregularity was sensed by motorman VK Gautam, who was driving a CSTbound train along the Harbour line.
“Gautam said that he felt a jerk and a clanking sound after the local he was driving passed over the affected part. He immediately alerted the control room, after which repair work was taken up and measures were taken to protect other oncoming trains,” a senior official said.
“Tracks bend due to the expansion of rails, which happens because of excessive heat. The services were regulated at a speed of 10 kmph for safety,” Narendra Patil, Central Railway’s chief spokesperson.
For the past few days, Mumbai has been boiling at 39 to 40°C. Sources said that during extremely hot days, the temperature of steel tracks can rise sharply, causing them to expand into wave-like shapes and affecting the normal gauge that crosses ties and ballasts. If undetected, this could lead to derailments.
“On such days, the metal rails are exposed to heat and continuously hammered by the wheels of the trains, leading to their expansion at the weakest spot in the track structure. What then happens, track bends in either direction,” a track engineer said. (Courtesy: Mumbai Mirror)
