If you have traveled on a train you’ll know that how different kinds of scenes come and go during the span of our journey. At times there will be scenes full of beautiful trees, mountains, valley, other times the scenes outside could of cement structures and at times in a few countries even slums. So in the face of ever-changing scenes outside what does the driver do? Does the driver move the train towards the direction where there are beautiful scenes and avoid the place where there are slums. Or does it ever leave the track?
