Even if NMGA to SBGA is connected, the main problem is the geographical constraint. SBC-KAWR exp reaches MAQ at 8 AM in morning by starting at 20:30 from Majestic.
KSRTC bus to MAQ starts at 22:40 , reaches Hampankatta by 6:30, this is also one of the reasons for the massive success of bus lobby in MAQ-SBC corridor. A train can never compete in terms of speed in MAQ-SBC sector. SWR should focus more on SL class passengers and obviously, removing HMRDA is the need of the hour.
