ISO certification abhi bhi hai Taj Express ke paas. And iska maintenance Delhi ke paas hai naa ki Jhansi ke paas so you can blame jhansi for it's maintaince. Jhansi ke paas secondary maintaince hai jisme water filling and normal coach cleaning hoti hai. Taj Express belongs to NR, New Delhi. Taj Express never had an additional counter of CC. and that too just for 1 coach.
Maine dekha hai SK, duronto ke baare mein tabhi bol raha hai. Very less and just a useless halt to satisfy political needs. Agar Gwalior ki dekha dekhi baaki jagah bhi halt hone lage toh SK and normal train mein fark hi kya reh jayega. Imagine MPSK halting at Agra and Mathura....
more... Similarly more capable potential stations are their like Surat and Agra for SK. You simply can't justify SK halt.
Agra Mein MHSK ka halt mila toh I said one thing. "Why should Gwalior have all the fun. Right?" Similarly yahi trend chalta raha toh saari SK bhi jagah jagah halt lengi.
