in the train timing it is said that the train stops at Ernakulam North/Town for 10 minutes and then proceeds to Ernakulam South/Junction where it halts for 2 minutes. Since the train is going via Kottayam there should be a reversal of engine at Ernakulam Junction and it cant take place in 2 minutes. So plz check the actual timing the train will halt at Ernakulam Junction.
