1. Looks like you know nothing about secr. Current rajdhani doing it in 90 minutes. This one doing it in 83 minutes. That too is old tt prior to tripling of lines. Tumhare sultanpur mein to triple line hoga nahi. That too this one will not be going to bsp and it's complex yard but to jalalpur directly through bypass. Uslapur has simple 3 pf structure and many trains skip at 60kmph.
2. At least 3-4 elocos are every time parked at durg end in raipur jn. If any of your friend have been to there you can ask him.
Three...
more... pairs of express trains are already making lr there as of now through the same route. Vskp-bgkt exp, bsp-tpty exp, krba-vskp exp.
3. If you can check days of operation of current raj(mon,thu) clash with cgsk and thus it is suffering from low patronage from bsp,raipur, durg. Bulk of its patronage comes from gondia and nagpur.
People here troll it for its low patronage and it's utility for CG state is low. You don't run a rajdhani for neighborhood state's benefit but according to originating state.
Thik hai IR chaahe to na cancel kare, dono ko ek sath chala lein, days of operation alag hai. 4 din raj service ho jaayega. 2 din ye aur 2 din wo. Apne ko koi problem nahi hai usse.
