Yes Kerala can byepass ERS and go via ERN saving a huge amount of running time. But it is not practical to do so with Venad Express bcoz a huge lot of daily passengers depend on Venad express. Most offices/schools/colleges are located in close proximity to ERS than ERN.Hence daily passengers will find it easy to board train from ERS.Also it is to be noted that a passenger train from ERS via KTYM is available only at 18.30 in the evening. Once Venad started to skip ERS and go directly to ERN. There was a huge protest from daily passengers.Many passengers including ladies started to jump from a moving train at Ernakulam C Cabin which is the deviation to ERS and ERN and many accidents were reported.Then Venad was again reinstated to its old schedule.
