Yes. But pax complaints sometimes seems to be a reason. Kerala SF was not maintained that well when it had CBC. I've noticed in CBE many times. So they eventually got rid of those rakes as Kerala SF is a prestigious train and people notice them in these trains. But i feel people should also notice the condition of poor Raptisagar. They shouldn't forget about it. Horrible maintenance by ERS and TVC SM for this train. I think even cleaning is not done at their side after such a long distance.
