This book came out in March 2013. I purchased it in September 2013 on my Kindle then. I follow the author of this book on Twitter and probably learned about the book from there.
I was in a reading rut after my son was born. I could listen to audiobooks on Audible but couldn’t pay attention when I read any book (physical or digital). I wanted to break this rut. So, I went back to my Kindle device and searched back to the first book I purchased on the Kindle. It turned out to be this book.

I loved some of the descriptions that he uses to describe the trains and railway buildings. He gave me the vocabulary to talk about sights that I see in my travels.
The red and cream locomotive screams into the platform with its assortment of coaches bobbing wildly.
Chapter 1: In Favour of Koraput and Bodinayakannur
Unlike the disjointed feeling one gets after a long flight, the railways allows for a gradual takeover. The landscape keeps changing, the houses seem different after a while, the food on the platform becomes less palatable (or the reverse) and the tea tastes better (or worse). And, by the time you arrive, you haven’t so much arrived as you have assimilated the destination.
Chapter 1: In Favour of Koraput and Bodinayakannur
The quaint old structures that used to house the station master’s office and booking counters have been demolished and replaced by banal, CPWD type boxy buildings, painted in a hideous urine yellow hue.
Chapter 7 : Dispatches from the Cauvery Delta
The book was an absorbing read and got me unstuck from my reading rut.
