The trial runs on Delhi Metro 10.47-km-long stretch between IP Extension and Maujpur started on Wednesday. The said section is the part of upcoming 59 km Majlis Park-Shiv Vihar corridor (Line-7) of Phase III, also known as Pink Line.

During test runs, the interface of the Metro will be checked to ensure that there is no physical infringement with civil infrastructure during the movement of train. Testing of various sub-systems of coaches shall also be done.

According to a Delhi Metro official, the Majlis Park-Shiv Vihar corridor, including the stretch on which the trial run was conducted, will open in stages by June 2018. A statement issued by Delhi Metro said: “The new signaling technology known as Communication Based Train Control (CBTC) will be implemented on this corridor and will undergo rigorous testing in stages.

The response of the train at different speeds, braking of the train and the interconnection with the Operations Control Centre (OCC) will also be monitored during the trials. The behavior of the track system and the Over Head Electrification (OHE) will be checked repeatedly.”

The section from IP Extension-Maujpur consists of nine elevated stations ~ IP Extension, Anand Vihar, Karkardooma, Karkardooma Court, Krishna Nagar, East Azad Nagar, Welcome, Jaffrabad and Maujpur.

The trains for the section are said to have arrived and are stabled at Vinod Nagar Depot. The section (IP Extension and Maujpur) consists of five special spans, including two steel spans, over the existing DMRC Red line (Line 1) and Northern Railway tracks between Welcome and Shahdara.
