Hi. Took this train till Arambakkam(a very nice station to railfan) on 24-Mar-2012 on a railfanning trip. The coaches were very clean and the power was ET WAM4. But a very slow train (never take it if you are in a hurry). A goods was sent ahead of us before Korukkupet. Reached Tiruvottiyur 30-40 mins late and got overtaken by 12578 Bagmati SF Weekly Express. At Minjur got overtaken by 12603 MAS HYD Exp. We had to wait here for a Gummidipundi EMU to overtake us (the ultimate insult).
Overall a very clean and neat train. Wasn't crowded and had a very relaxed run.
