The train from Vasco to Howrah provides awesome treat to the eyes on the first day, all the way from Vasco to Guntakal, the second day too is awesome all along the Eastern Ghats, but this train is a good option till KGP.. For passengers bound to Howrah this train is quite inconvenient as it usually doesnt reach before 22:45 or so (usually 20 to 25 mins late).. For railfanning and photography of natural scenery this is one of the best options with two full days to spend..
