Officials said the drill on 'intervention of rail coaches and countering of terrorist elements' was conducted by the National Security Guard commandos in the wee hours at the Dhaula Kuan station where the 'black cats' also used their modern weapons and equipment used for neutralising terrorists and rescuing commuters.
The Dhaula Kuan station is an important passenger facility on the sensitive and faster airport express line of the Delhi Metro.
They said the strike team of over 350 commandos also conducted a similar drill on the coaches and depot area around the Dwarka Sector 8 station along with a small team of CISF personnel who secure the Metro network.
