Not a bad experience I Would say. It was moderately good. Good for railfanning but no Pantry Car & my coach being 2nd last meant that I couldn't get anything to eat, only ate Lays & Brittania Cake in my whole journey. Had aches in some parts of my body but it literally vanished after I got a nice sleep [Or maybe happiness of coming home made it disappear ;) ].
If I have to go home, I dont care whatever the class is- be it CC, Sleeper or even General. Ghar jaana hai to kisi bhi haalat me jaana hai. But Its just the opposite in the return journey.
And...
more... regarding travelling in BGP GR, It would be an option for travelling again only on Mondays unless another rake is arranged.
