Video narration
Aapke saamne rail hatane ki taiyari hai; dal kaam shuru karne ko taiyar hai. Lekin tareeka tay karne se pehle ek baat saaf honi chahiye: is rail aur isi kaam ke liye kaun-sa nirdesh lagu hai? Indian Railways mein har rail ko sambhalne ka ek hi tareeka maan lena surakshit nahin. Rail kaun-si hai aur kaam kya hai - inhin ke anusaar lagu RDSO nirdesh, yani us rail aur kaam ke liye sveekrit tareeka, pahchanen. Maujooda aadhikarik dastavez aur uska sanshodhan dekhen; keval purani jaankari, suni-sunai baat ya kisi doosre kaam ki prakriya par bharosa na karen. Phir usi nirdesh mein diye gaye sveekrit tareeke ki pushti karen. Nirdesh spasht hone se pehle kaam shuru na karen, aur anumaan se koi tareeka na apnaen. Agar lagu nirdesh ya sveekrit tareeka pakka nahin hai, to ruken. Pehle pushti karen - phir aage badhen. Rail chalane se pehle, nirdesh pakka - tareeka tabhi.
