I have never seen this train ever arriving Carmelaram at its scheduled time. In fact there are people working close by in tech parks who use this as an option to go towards SBC & BNC. They are very confident of it always arriving post 7pm. Controlling from SBC division of trains from DPJ till SBC is quite bad. Same is observed in the morning trains as well ( CAN YPR & TN-MYS, )
