Thank you for your kind explanation.
1.As per the point how can a person sit on the floor for long time also implies to the person who is travelling in sleeper class with waiting list ticket by sitting on the floor. Furthermore we are providing Television entertainment so there may be a chance to a passenger to feel without any pain.
2.Required space for a passenger: This may be possible by making the compartment with double floor with increased height as compare to existing coaches’ height.
3.If...
more... anybody gets painy feeling they can change their sitting style (may be use of pillow also….)
Anyway if possible please make a trial in any one of the train and collect passengers’ feedback.
Thank you for sharing my views in this thread.
