Presently the Windows are designed for the AC 3-Tier Lower Berthed Passengers only.
Requested our Indian Railway that necessary small SEE THROUGH WINDOWS have to be provided for the AC 3-Tier & AC 2 Tier Middle and Upper Berthed passengers also so that they independently ascertained the train movement and stations.
The Lower Berthed passengers are totally free from Middle and Upper Berthed Passengers regarding the passing /present station of the train.
