The erstwhile Kingdom of Mysore established Mysore State Railway for improving rail connectivity, right after the commissioning of Madras Royapuram–Bangalore City railway line in 1879.

Land acquisition of about 160 acres (65 ha), especially 25 acres (10 ha) near Mandya alone have been done as part of double line and improving stations between Ramanagaram and Mysore Junction.
