A quick suggestion is to merge the following:
16515/Yesvantpur - Karwar Express
16516/Karwar - Yesvantpur Express
16539/Yesvantpur - Mangaluru Jn. Weekly Express
16540/Mangaluru...
more... Jn., Yesvantpur Weekly Express
16575/Gomteshwara Express
16576/Gomteshwara Express
This would result in less rake usage and can be added to a single train and made long enough to have more coaches, providing better connectivity from coastal Karnataka to the city capital. With daily service, we provide quality. Travel and make more tickets available. Do share your thoughts on this.
