Delhi Metro Rail Corporation [Dmrc] — major issue in metro ac service :yellow line

Address:	110029

It has been noticed from past few months as in a running metro the working tendency of the ac gets reduced to the significant level followed by a decrease in the oxygen level n the metro. Hence causes fluctuations in the body physiological parameters like bp, pulse..

Myself have experienced it several times and confirmed through my near and dear ones too who r regular dependent traveller complaining the same issue.
... Me being a neuro student from renowned central govt. Hospital would like to request you to kindly consider this matter seriously as decreased level of oxygen in the running metro could lead to brain anoxia to any of the age and gender
