I would like to share my experience while travelling to Kharagpur from Bangalore on Feb 20, 2009 in Yeswantpur Howrah Express.
I had taken a 3rd AC ticket, and was wondering if there would be Power Points in the individual cabins or not. I tried reading lot of blogs, forums but could not get any info.
While going from Bangalore to Kharagpur, our compartment had Power points for all the cabins (8 seats group). While the adjacent 3rd AC coach had power points in every alternate cabin.
This is mainly intended for charging of mobile phones, though even laptops can be charged with this. If the circuit breaks because of over load in the compartment, ask the attender to pull the switch again so that all power points are funcional again.
However while returning my coach (3rd AC) has power points at every alternative cabin.
The railways has really improved a lot over the last couple of years.
If you are planning to travel for a long distance with the airfare rates going so high, travelling in train is not a bad option at all.
Cheers
