It is well known that the Chennai metro rail stations will start functioning in the first quarter of 2014. Here, the passengers will have to scan their baggage before entering the train. The officials at CMRL (Chennai Metro Rail Limited) stated that scanning will be done in order to ensure safety of all commuters.
They also added that they have called for tenders to install such x-ray baggage scanners. Large stations may have two stations, whereas the normal ones will have just one.
