If the Rajdhani is diverted via AY, it will definitely gain an extra stoppage at AY. The LJN-AY-BSB route is still not faster than LKO-SLN-BSB route [ I think the mps is similar , correct me, if I am wrong], but the former takes a longer loop.
please wait...Translate to HindiAgar Rajdhani AY ke raste se mud gayi toh pakka se AY par extra stop milega. LJN-AY-BSB ka rasta abhi bhi LKO-SLN-BSB ke raste se tez nahi hai [Mujhe lagta hai speed same hai, agar galat hoon toh sudhaar karna], par pehla rasta lamba ghoomti hai.
