I am really impressed by SR's controlling in MS-TPJ section. Even with single line(from CGL-MYP there was single electric line) and diesel chord line in the earlier days, all trains got excellent priority and maintained good speed. I was impressed by Rockfort's performance in particular. Never failed to arrive BT. Even when the single line was electrified, when I travelled in Pallavan, the train led by P7 touched MPS of 110 from VM to TPJ all the way though it was a single line. MS side controlling is better than that of MAS probably due to lesser congestion.
