Delhi Metro Rail Corporation [Dmrc] — Regarding the coaches of green line metro

The number of stations in green line are large and the it is connecting atleast 3 more other lines of metro which lead to the massive crowd but the coaches of the metro are still 4.
It leads to massive crowd and may kead to theft and misbehave with the ladies too. So it is requested to make the coaches of metro atleast 6 in the green line metro
