AC Duct design errors in new AC coaches


Dear Indian Railway team,

I would like to highlight to our Indian railway for some AC Duct design errors in new AC coaches. There is a major fault in Bogi designing during AC blower location planning. If you see the distance between Upper Berth Passenger and AC blower is hardly 1 to 2 feet. The Person who has been allotted the upper berth has to face AC Air flow directly on his body which is not feasible for anyone. Major problem comes in the night when the passenger has to sleep continuously for 6-8 hrs. Actually Old AC coaches were having Flaps for controlling the AC Air flow direction. If someone feeling hot or cold can change the air flow direction as per situation but new AC coaches are having fixed holes and a major part of the airflow goes by default towards upper berth passengers. This situation keeps upper berth passengers in uncomfortable conditions. I would request our Railway coach design team to look into this matter and help all the passengers.

I am very much available for an in-person meeting to discuss the issue in detail because at the end of the day, it will help our nation’s citizens in a big way.
