The broad gauge line between SBC-GY was opened in January 1983. This involved the following things -
1) New Broad gauge link between Baiyyappanahalli (BYPL) and Yelhanka (YNK).
2) Gauge conversion of MG line between Yelhanka and Dharmavaram.
3) New BG line between Dharmavaram and Gooty. This BG line ran parallel to the Pakala-Guntakal MG line between Dharmavaram and Kalluru.
