Indian Railways — Pest like cockroaches in trains

I am sorry to say that i was travelling with my small son in Indian railway, Netravati Express, on 20-10-08 by A>C three tier and it was a horrifying experiance, there were small-small cockroaches running around in the Train compartment. My son said we should not travel in the Cockroache express, if this is the impression on mind of small citizens of india, what will they think about INDIA. Please take care of small things in future.
