Manwar Sangam should lose couple of stops [eg Gaur], be speeded up and get extended to GKP [with stoppage at KLD].
The problem with Saryu Express is it's timings. It already starts at possibly the worst time possible from MUR at 0230 hrs, I think. Extending it to Gonda will exacerbate this issue. A better solution would be to just introduce an overnight crawler from ALD to Bahraich via Gonda. That would be better, IMO.
