To fir old delhi ka kya karenge? Only passing trains..nahi yar it deserves better..long dist trains like Vaishali, Puru, Poorva, BP Mail that cover many stations & zones including those from where short distance trains start, should come on the other side of Yamuna.
Pattern can be like this: BSB-NDLS 3 dedicated trains (SG, Mama, MUV-super), ek ko yamuna k is paar lao, baki do ko us paar rehne do.
