There is no comparison between Gomti and PPTA SF, Gomti acts as a lifeline in the CNB-GZB stretch where hardly any trains are for intermediate stations.
For stations like JJK, PHD, and BNT it is only a morning option to travel towards ALJN, NDLS. The rush is so much that NCR has to run MEMU trains like 04159, and 04189 for ETW and ALJN.
