Central Railway (CR) continues to be plagued by problems, both major and minor, adding to commuters' woes and signalling the fragility of the suburban train network during the monsoon. Just a couple of days ago, on June 29, the Harbour line was affected at Mankhurd and Mahim, when apparent mud erosion below the tracks washed off part of the ballasts. To top it all, a derailment of an engine of the Mangala Express at Kalyan on June 30 affected local trains.
