The central government had last year cleared UP Chief Minister Yogi Adityanath's request to rename the station, despite protests raised in parliament by various parties.
This morning, Aam Aadmi Party (AAP) leaders were among the first to tweet.
Arvind Kejriwal, the Chief Minister of Delhi, tweeted in Hindi, "If you vote BJP, then names of cities and stations will change. If you vote AAP, then the future of your children will change."
There were more critical tweets.
The Mughalsarai station was set up in 1862 when the East India Company linked Howrah to Delhi by rail. Since it was an overnight stopover for caravans, it was named "Mughal Sarai (Inn)".
Deen Dayal Upadhyay's connection to Mughalsarai is his death under mysterious circumstances at that station in 1968.
On his birth anniversary last year, the UP government put up the proposal to rename the railway station.
