He called the Delhi Metro's Green Line to Haryana a "gateway to development".
In his inaugural speech, PM emphasised how the Metro has had a positive impact in Delhi-NCR region and will "facilitate an ease of living and travel in Haryana's Bahadurgarh in the same way".
He said: “I congratulate the people of Haryana and Delhi on the commencement of this new section of the Delhi Metro. It is gladdening to see Bahadurgarh connected with the Delhi metro. This is the third place in Haryana, after Gurugram and Faridabad to be connected like this.”
The route has seven elevated stations in total, of which four are in Delhi (Mundka Industrial Area, Ghevra, Tikri Kalan and Tikri Border) and three in Haryana (Modern Industrial Estate, Bus Stand and City Park).
Modi said: “We also want to boost Make In India by making coaches of the Metro in India itself. Several nations helped us in the making of the Delhi Metro and other Metros, and now, we are helping other nations by designing coaches for their Metro systems.”
He said the Metro used at least "75 per cent India-made products and equipment"..
Modi also advocated the need of integrating transport system in India.
"Earlier, every state used to work in its own way. All the decisions were made by the state governments, ministers and departments and that's why there was no policy for work related to the metro.
"But under the 2017 Metro policy, all these issues will be addressed. No matter where the metro is made, a set standard will decide on how things will work," he said.
He also mentioned a "regional rapid transport system", which will connect Delhi to Sonipat, Alwar and Rohtak in the coming days.
