That electric train is a nice image. India has plenty of opportunity to take advantage of cheap solar power and push cargo around the state with it. They are adding more electric vehicles by the day, which will help places like Delhi become more breathable, though the last time I was there, farmers were still burning the fields, causing a lot of air pollution in Delhi during the burns. The manufacturing base is improving, so you can buy relatively cheap vehicles.
Your money goes further in India. Their tax collection is pretty weak, so they print money to fund government spending which usually means higher inflation than we're used to in the US, but they're starting to get a better return on their infra spending as the country is lifted up via the use of the most recent tech (trains, smartphones, fiber, solar, battery, etc...).
It's been fun watching the country and region develop over the years. They still have a ways to go, and in some ways I think I'll miss the old chaotic India. You don't find cows wearing decorative garlands in downtown Chicago or New York. I bet whatever India transforms into, it'll hold some of it's unique charm. That's my hope anyway.
