After GC of POY-PTJ maybe POY-PTJ,POY-PGT,POY-DG sections can be doubled and electrified because now goods traffic has begun from DG-PGT and after few months all the goods trains which is going or coming from kerala to southern districts will be diverted in this stretch and the station like PLNI,POY,UDT,ODC are only capable of holding more than 35 cars and others cannot hold more than 25 cars so in some years the whole goods traffic will be diverted so they can better double it then electrify it then they can upgrade other stations.
