in NFR KIR division each Sunday block is taken so we can see no train practically departs NJP after 1000 & in Up direction also most of the trains are held up for several hours because here Sunday is the official track maintenance work...So Sunday seems to be a holiday for the Operating deptt,but not for the Engineering deptt.but I dont think in Konkan such blocks are taken...if you dont take blocks,bring BOBYNs,change the ballast regularly,avoid Alumino Thermit welding,properly strengthen the tracks using plasser machine,then these incidents will take place more frequently.
