Ahead of throwing open the track from Yamuna Bank to Noida across the state border from east Delhi, Delhi Metro began trial runs on Saturday on a section of the route, a Metro official said.
The trial run, which began at 10 am, was conducted only till the New Ashok Nagar station in east Delhi.
According to Delhi Metro Rail Corporation (DMRC) officials, trial on this section will go on for 10 days and subsequently, the rest of the route till Noida city centre will be covered.
It will be for the first time that the Delhi Metro will cross into another state -- Uttar Pradesh. The new route is 13.1 km long.
"The trial runs will go on for approximately a month's time, during which the section will be tested for signalling, tracks, telecommunication and interfacing of trains working with different systems. The interim stations on the route -- Akshardham, Mayur Vihar Phase 1 and Mayur Vihar Extension -- will be elevated," a DMRC spokesperson said.
The trial runs will not affect the running of the trains in the already functioning portion of the route, that runs till Dwarka in southwest Delhi.
"The Yamuna Bank to Noida section is scheduled to be opened for the public by the end of this August. With the opening, this route will have a total of 42 stations and its length will be 47.2 km. This will also become the longest operational section of the Delhi Metro," the spokesperson said.
In the 13.1 km new portion of the route, there will be 10 stations of which four will be in Delhi while the rest will be in Noida.
The total travelling time on 47.2-km route will be 90 minutes.
