Since Intercity and other Non AC trains are not generating profit anymore so Railway is not introducing Intercity type trains.

Only Gomti Express is present as of now which is having only Three(2 CC and 1 HA) AC Coaches. Proposals have been sent for increasing AC coaches but its RSA partner New Delhi Agra Intercity is not having any such demand so AC coaches are not being added.

Although DFC has cleared the track congestion but Platforms, Maintenance lines and yards are still congested so still it is challenging to get new train introduced.

Both Lucknow and Kanpur are already having many many trains with faster connectivity so passengers can use those trains for faster connectivity however these cities are having much limited options and for achieving 1 Trillion economy of UP, faster connectivity is required for these small towns as well.

Well the fastest train to LKO is Tejas which is still the not that fast .. many alternatives still exists for these cities as well...
on top of it .. people are avoiding shatabdis and vb due to higher fare..

IR rakhe .. Shatabdi ko .. isko har station par rokiye .. should not reach lko before 8 hours...

There might be many stations enroute which also would not have any train to any where else …
Things are not planned like that .. you can not build railway line to each village … you build alternative transportation system which are more feasible and viable ..
like phaphund and Kanpur will never have a Namo train system … or Kanpur is a big city but it does not have a direct international flight to anywhere ! For that matter even Lucknow is not connected with London but Delhi is .....

and that’s how people of Lucknow traveling abroad by coming to Delhi and catching plane to European destination apart from some gulf cities which are connected … this is called Hub and Spoke system .. and this is what is going to happen with IR in the future ..
these city might not have a direct train to Delhi in the morning but would surely have multiple connection to CNB and near by major centres (10000 daily trips) … because the trips to the near by cities would be much much greater than the trip demand to Delhi ( say 100 daily trips …)
In future … IR would expect people to move to a bigger hub via Vande Metro or local train and then change and continue there journey to the bigger city ..
This is what is viable for all …
