While its time was around 5pm ( ideal time from office leaving point of view) or thereabouts , it used to run late by 20-25 min making it an ideal option for lots of people working in ORR belt ( Sarjapur Road, Kadubeesanahalli) . It was a quick option for people to got to Bypl for onward metro connectivity as well. Revised time will be delayed by 2hrs. Might be following ERS-SBC intercity express
