If you are a regular traveller of this train you will understand my words. the train now always late by half an hour at ktym and fromsshorn u r diesel engine takes the charge instead of electric and the train moves faster and reaches every station before five or ten minutes. earlier the train was completely hauled by diesel loco and the train was right on time at Kottayam, Shornur and Mangrove. now it hauled by electric from nagercovil to Shornur and late by half or more hour. that's what I mean
