Thanks for clarifying...to be more realsitic they could have added some side sprayers to simulate heavy rain with winds.

Covered wagons are meant for payloads that may suffer damage from the elements. Hence 'covered' ;-). The wagons are on their usual bogies. They seem to be of lesser length than regular BCNA wagons to compensate for increased height/capacity in order to keep axle loads within standard limits.

Each covered wagon is subjected to the water ingress test. Those that are 'water tested' successfully are certified with WT text on the side.

Ashish is right. One can see Light green colored pipes with spray nozzles to spray water from outside. This could well be for dry cargo.

Dear Shikhar, I think Rishiraj meant leakage of water from outside to inside. The wagons may be meant to carry cement bags or foodgrains etc. Notice the position of wheel. Could the wagon body have been kept on a temporary bogie?

is the container meant to be sealed ..? why not go for a tanker construction ..?

nice catch

The train at the background looks like Matyagandha express.

These are frequent visitors to PNVL - BSR area.

Good catch Sir.

This is a marine tank container used for import export of liquid cargo.
