Would it not be better if we have a TT suitable for Tumkur to Birur passengers -- something like dep at SMET 1930 Tumkur 2330, KJM 0115, KPD 0530 to reach MAS by 0830 (can go to Egmore where PF are relatively free). Again return start from MAS or MS by around 1930 to reach Tumkur by 0430, SMET by 0830.
At present, TT is suitable for pax from SMET only and serves as another additional train from KJM to MAS.
