Both 22681/82 and 12691/92 must be made tri-weekly each so that there is a 3rd overnight train from Chennai to Bangalore. Extension to TBM will increase patronage and reduce parking issues at central.
22681 and 12692:
PER 04.15

22682 and 12691:
TBM 22.30
Egmore 23.00/23.10
PER: 23.40
No other change in timings.
We don’t have a 3rd ONT between Chennai and Bangalore inspite of heavy passenger traffic even after 20+ years. Hope railway authorities consider this suggestion.
