seems you have not understood clearly. There is a direct route from ERS/TVC to MAS via SRR where in a line bifurcates towards MAQ. Earlier all trains used to go till SRR (and have a loco reversal) to move towards TVC. Even some trains like Netravati express (correct me if i am wrong) used to run via GTL-RU-SRR and had slip coaches towards MAQ.
