Vaigai வந்துருச்சு, ஆசையில் ஓடி வந்தேன்

Unfortunately there is no solution to this. Fencing can make it safer but even then it's not advisable to run trains at top speed blindly in fog. You never know if someone might be stuck in a bus or truck at a level crossing or even a fallen tree on the tracks which can be a disaster.
