Thanks a lot Khalid Bhai , helps a lot. I too had similar doubts, regarding refrigerated vans.

Looks like HCPV-cum-VPAC (air cooled parcel van) coach.

They appear to be modified Refrigerated Vans,probably earmarked for hauling perishables/Cold-Chain items attached to high speed trains.
Note the box beside the coupler which appears to be a Power Intake junction box which is also found on Rajdhani type trains having EOG/HOG format.
The pipes protruding above the black box may be diesel engine/generator exhaust which is probably situated inside the smaller part of the coach.

Kharad Zarir Variyava Sir- Sure i shall take care from next time onwards what you have advised me. and i am not aware of how to remove water mark.

Abhishek, one request. Please avoid watermarking on the topic of the snap, in this case the Wagons. You have already watermarked the images at 2 locations, top left and bottom right; so i fail to see why you have bookmarked the wagon as well. Again, its not difficult to remove the watermark as you would be aware.

High time a integral design like this came up.
One of the biggest cause of fires after derailments is the member of ladder type chassis piercing the tank.

IR did away with chassis on body for passenger coaches more than 50 years ago.

nice pic!
@ Jay sir: Sir, i have query about this design, i don't know much about the US railway network, but considering IR, do u think eliminating the chassis is a good option?

Thanks for this photo! It's about time IR adopted this design. This is the standard here in US. The weight saved in eliminating the chassis can now be used to increase the tonnage capacity of the tanker without increasing the axle load.

Great Shot!
