UP Roadways works in set route & CNB-SRE is via ALJN-ETAH-BSC-MTC.
No private bus ply in CNB-ALJN while Janrath is just a slightly faster AC version of normal bus!! UPSRTC Volvo will be a different story!!
And yes, if UP Roadways/State Ministry would have been utilizing Exp Ways sensibly, you may not find such number of Private Operators!!
