if your train is going to reversal or there is a 30 mins stoppage at NGP , then you can make a dash to cotton market/santra market which is on right side of train if ur train is going to delhi/hwh and on left side of ur train is ur train is going towards south..u can get the best nagpur oranges at very cheap rates at any of the wholesale rates ..will take 5 mins to exit 10 mins to buy and another 5 mins to get back ...the wholesale market is just on the footsteps of the exit on Santra Market side...
