The Indian Railways on Sunday introduced a first-of-its-kind see-through vista dome coach on its Vizag-Kirandul passenger train. The coach which costs Rs 3.38 crore contains large glass windows and an observation lounge that offer passengers a panoramic view and has 40 double-wide reclining passenger seats that could be rotated 360 degrees for a better sightseeing experience. Railway Minister Suresh Prabhu flagged-off the train through a video link from Bhubaneswar.
