Modi boarded the train at the Lok Kalyan Marg metro station to participate in the event, where he inaugurated the Dr. Ambedkar National Memorial at 26, Alipur Road, on the eve of the Dalit icon's birth anniversary.
He deboarded the train at Vidhan Sabha metro station, nearby the memorial, and after the programme ended took another train to Lok Kalyan Marg metro station on his return journey, DMRC officials said.
Services ran normal on Line-2 during Modi's travel, he said.
The prime minister's official residence is 7, Lok Kalyan Marg in the heart of the Lutyens's Delhi.
26, Alipur Road is the place where Ambedkar lived during his last days before he died in 1956.
The Prime Minister's Office tweeted photographs of the new memorial.
"This is the place where Dr. Ambedkar attained Mahaparinirvana on 6th December 1956," the PMO tweeted.
"Prime Minister @narendramodi had laid the foundation stone of the memorial on March 21, 2016. The memorial of Babasaheb Ambedkar, the creator of the Constitution of India has been given the shape of a book," it said.
An Ashokan Pillar stands in front of the book-shaped building in the sprawling premises. Iconic gates, Bodhhi tree, musical fountain and a meditation room are its other features.
"This memorial will serve as one of the vital focal points that will bring Dr. Ambedkar even closer to today's younger generation," the PMO tweeted.
Previously, Modi travelled by Delhi Metro on December 25 when a corridor of the Magenta Line was inaugurated.
