I am SR , let me tell you , SR is the laziest shit to start any kinda new trains. Whatever new train it is , its always other zone that starts to TN or KL. Lol. SR wants to avoid taking responsibility of PM .
They avoided Sabari SF version with PM at TVC, They avoid 12163/64 to handle in Basin Bridge when CR was ready to give back the train to SR when they changed it to Central station lol.
