i check a route i want to make and as i know some how i check sections wise. For ex: i want to make a train from VSKP to JP first i see how many trains are there and what route they are taking. As i dont want to take that trains route i check little or more diversion. and check trains in that route to JP . to JP u can go via BZA also and via RGDA/R/BSP route also. like that.
