Apki baat sahi h bhai. Agar railway planning ni kregi toh engine to ndls me bahut se idle pade huye h. Bahut bar dekha h guds train ko terminate/rest station k outer pe 3-4 hours tk khada krk fuel waste krte h. Thoda mehnat kre toh exp train ko outer pe rok guds train yard me laye/ jo bi fuel waste bchegi alp & lp ka overtime bachega.
