Due to a weld fracture observed in Delhi Metro Up Line (going towards Dwarka) section of Blue Line from Karol Bagh to Rajendra Place stations, a precautionary temporary speed restriction (TSR) of 25 Kmph was imposed on trains on Monday morning.
However, services on the entire Delhi Metro Blue Line are running normal since then, with no impact as such on the regularity of the services. There was initial bunching of trains when the TSR was imposed around 8:50 am to regulate all the trains on the line accordingly.
Delhi Metro to undertake maintenance work on Blue Line at night
To avoid disturbance to regular services in day time, Delhi Metro
maintenance team will take a maintenance block to carry out repairs (good weld) on the Blue Line after the closure of services in the night.
How are welds damaged?
The welds, at times, develop fractures due to change in temperature/weather conditions. It generally happens in early morning hours. Monday’s defect was also noticed in the morning and accordingly, it was safely secured, as per the established norms and procedures.
Running trains at restricted speed is safe and as per standard practice. All the tracks are properly maintained and inspected by maintenance teams through physical patrolling at night on a daily basis.
