Although being a crawler, this train is easily the most important train from West Bengal to the north-east. The train is quite prioritized on its route. Kamrup Express being late is a rare phenomenon, although seen sometimes in the winter season. The train is ISO rated, but none of those standards are seen in the non-AC classes. The AC coaches are also not the best maintained coaches, but get the job done. The bedsheets, pillows and blanket provided are pretty clean. Charging sockets are seen in all AC coaches, but none of the non-AC coaches in which I have travelled had Charging sockets. The train has many stoppages en-route, hence many general and daily travellers get into the Sleeper class coaches in this train, hence long distance travellers should opt the AC classes. This is the only daily train from Howrah to beyond Guwahati and towards Dibrugarh, hence remains full throughout...
more... the year. Pantry is on the better side. I have not seen the pantry staff overcharging the people yet in this train. Snacks and fast food provided from the pantry are excellent. Last time I travelled a month ago in AC 3-Tier, the attendant told me that the OBHS facilites had been removed from this train, due to which the cleanliness standards have also degraded in the train, which can be one of the negative aspects for the passengers, especially the long distance travellers.
EDIT - As of 20/08/2019, I have travelled in this train couple of weeks ago and am presently in the train, I have to make some changes. First, the train has got its OBHS services back and these guys are active, they come and clean clean the coaches on a regular basis, atleast the AC classes. Food is as always good on the train. The pantry guys have started to provide bills to customers on demand. They also have a tagline on the backside of their uniforms, 'No bill, no charge'. The train has not been utkrishtified yet but there are Vinyl wrappings in the restrooms of both the rakes I have travelled in the last couple of weeks, as well as the one I am presently in.
