A few months ago, I wrote an open letter to Boris Johnson about litter in London, especially on the tubes which at times are a disgusting mess of food scraps, drink cans and newspapers. I didn’t have a response from Boris, so put my quest for cleaner trains aside until I noticed a post about trains in Mumbai. http://janmerryauthor.blogspot.co.uk/search/label/anti-litter%20campaign
India is not known for being spick and span and their trains suffer over-crowding and harassment issues, but at least they're clean. I contacted the blogger and asked if all Indian trains were so clean.
Here is her response:
|Joe Brucker Taipei train|
|Spot the difference: London train|
Its surprisingly clean on the trains - what you might see out of the window is a different thing entirely! You would never see all that paper like in your post - someone would have nabbed it to re-sell it within minutes. http://mumbaimag.com/train-spotting-mumbai-local/
