It's high time that Chamarajnagar gets developed as a Terminal and some trains like Gol Gumbaz Express, Basava Express and some majority of trains not having Primary Maintainence at Mysuru get extended to Chamarajnagar, it'd serve Piligrims to Nanjangud as well.
I guess some Superfast Trains to destinations like Jammu/Amritsar/Chandigarh, Guwahati/Dibrugarh/Agartala, Mangaluru (essential) would be beneficial to Mysuru.
