The trial run of India’s first underwater Metro Rail below the river Hooghly flowing by Kolkata, was put on hold at the last minute.
The train testing will be conducted after the rakes arrive at the terminal station so that the Esplanade-Howrah Maidan stretch may be given the all-clear for operation.
The historic underwater run of the metro is hihgly-awaited by many.
The two six-coach trains have been readied for trials as part of Kolkata East-West Metro Project.
The two rakes would soon traverse from Esplanade to Howrah Maidan beneath the Hooghly river, passing via Howrah Station.
The two rakes had been operating with the aid of a battery-driven locomotive during testing within East-West Metro's Salt Lake depot for the previous week.
It was essential to get the rakes to Esplanade before the train testing on the Howrah Maidan-Esplanade stretch could start.
