Summary:
Due to the snag, the Operations Control Centre (OCC) is frequently losing contact with the trains along the 50-km corridor. AdvertisingThe Blue Line connects Noida City Centre to Dwarka’s Sector 21. Delhi Metro’s Blue Line, which carries around 9 lakh people daily, was hit by intermittent signal failures during the morning rush hours on Thursday, a day after a similar glitch left thousands stranded. The OCC is the metro’s centralised control room. Under the alternative arrangement, trains are controlled from certain stations, which naturally slows down operations, triggering a cascading effect along the entire section..
