Simran is nice and accurate. I dont know whether you have tried KR's '' Current Train Position'' which has been around for the last ten years or so. Here you have the ''simulation'' of all train positions on the KR track which is updated every few minutes. As it is a single track, you can find out about the crossings ahead and overtakes. Ideal also if you are on Matsyagandha with a mobile internet device. Here is the link and your feedback welcome.
