The coaches are very very antique and from first glimpse itself you will understand the "age" of coaches.
But eventhough they are old, but till the maintenance is good, specially AC coaches. Sometimes rats and cockroaches are visible in AC coaches but for that i have written for "pest control" in complaint book. Kindly if you board this train and see these pests then immediately talk with attendent. If Pest control is pending, kindly fill complaint register. Don't ignore because sometime these rats even chew up the luggage (Personally have once suffered).
