overtake isliye karti hai kyun iski timing shri shakti se pehle hai. agar ye 1 hr late bhi ho to bhi ye aage jaakar cover kar leti hai isko.
Ek bar isko overtake nhi karvaya tha katra tak shri shakti ko hi aage rakha. to hua yeh ki shri shakti to right time pahunch gi lakin ye 1 hr late pahunchi. shri shakti ko overtake karne se yeh dono train right time ya mostly before time hi katra pahunch ti hai
