The then Prime Minister Jawaharlal Nehru had flagged off the ER's first EMU train which ran between Howrah and Seoraphuli stations on December 12, 1957, ER general manager Harindra Rao said.
The then Railway Minister Babu Jagjivan Ram and Chief Minister of West Bengal Dr B C Roy had also been present on the occasion.
"It is a historic event to celebrate the commemorative run of the EMU train," Rao said before the journey commenced from Howrah station for Seoraphuli.
At present ER runs 1393 EMU trains -- 476 in Howrah division and 917 in Sealdah division -- every day.
Electrification of HowrahBarddhaman Chord and Calcutta Chord link were completed in 1966, which ushered in a new era of faster and comfortable train journey for commuters, Rao said.
