I am not against bypassing Bangalore. I already mentioned this in my post, by saying that passing through KJM/BAW is ok. What I meant was bypassing through BWT-CBP-GBD (if that route is constructed) seems too much.
BWT/CBP/GBD are way too far from the city and poorly connected to act as a bypass stations.
Besides,...
more... a train taking the JTJ-SBC/KJM - GTL route is running through that route solely for giving a Bangalore connection. Otherwise, there is no point of running trains to Guntakal via JTJ in a roundabout route. For trains coming from CBE side, the SA-Hosur-BYPL line is a shorter route, and for trains from AJJ/KPD side, the route via RU or PAK is the shorter one (and also has TPTY, which always draws a lot of passengers). So, I felt there is no point in running via JTJ, BWT and then running via CBP to GBD completely avoiding BWT.
