Shanu Babar loves train journeys so much that he began documenting his.
Soon, others joined him.
Shanu Babar was five years old when he first boarded a train. It was the start of a life-long love affair.
In college, he documented a series of train journeys across India for his dissertation.
This selfie was taken in February 2015 at a station in Trivandrum, capital of the southern state of Kerala.
On 21 July 2015, Mr Babar launched @windowseatproject to record his journeys on Instagram.
The "window seat", he says, has always been his favourite spot on a train.
It was also his vantage point for this photo of the colourful Ernad Express, with each coach advertising a different brand.
Travellers often carry elaborate home-cooked meals for train journeys.
Mr Babar says they remind him of his family's "feasts" during their annual trip across the hills of western India.
The menu would include curries, breads, rice and masala puris, a deep-fried Indian bread where the dough is stuffed with spices.
Photos from contributors kept pouring in, turning @windowseatproject into a crowd-sourced visual library.
This, Mr Babar says, is how dairy farmers across India transport milk from rural farms to urban markets because
there is no place inside the trains for so many milk cans.
