What has been the funniest/weirdest thing that has happened to you while travelling in the Delhi metro rail?
Animals on the metro trains? That sounds strange. Can you tell me more about that?
Yes, in 2015, there was a video that went viral showing a monkey riding the Delhi metro while holding onto the overhead bars. There have also been reports of stray dogs and even rats on the metro trains at times.
