Asli Dhokha dekhna hai toh Shutter Waali image dekho. First image is of Erstwhile Vistadome of Deccan Queen.
For rest of images,
At the Very least these people will get Cab Ride like feel in Vistadome. Closest to Locomotive.
Having tried same in Deccan Express, mainly because I wanted Executive Chair Car Benefits, the view was indeed an added bonus.
