If you are thinking of booking in chaircar of garib rath or yuva exp by assuming that mumbai to delhi or viceversa in these both train is just one night only,then i beware u,plz think twice....your that one single night would become the nightmare for life....your travel night would be as below:
whole night the lamps will be ON.
WL and gen ticket pax will be there in between bdts-st/brc.
No...
more... extra space for legs to stretch.
Min halts and of less time,so that you can't even stand up and walk for freshness.
No place to even keep your head while sleeping.
No pantry.
Steady and old-hard-rusty seats.
Old ICF chair car rakes which will feel like more jerking as compared to sleeper coaches.
Next day when you will arrive destn,u would be like getting bailed after a one night jail.......;-(
