Today, while travelling to Aurangabad by road, came across this site where a small "not seen before" shunter was seen atop a trailer truck.It was seen again later between Ahmadnagar & Aurangabad. That is where I took some pictures in detail and spoke to the truck driver.
This shunter is being taken from High Explosives Factory Khadki to Metal & Steel Factory, Ishapore, near Kolkatta.Presenting some pictures of this unique sight.
Some portions have been blacked to protect identities.
First spotting of the shunter on a trailer truck. Between Pune and Ahmadnagar.
