I'm not sure about the earlier number of AC's on Kovai, but for the last couple of years it has been a single CC. Kovai and Intercity (Bangalore-Coimbatore) share rakes which interchange at CBE.

Is the Kovai down to only ONE AC Chair Car nowadays?? I've seen both this and the MAS-CBE Intercity run with 2 AC Chair Cars. Is this regular now?
