It always happened in Indonesia.During festive season, they are exercising on a train. Why do I say so, since the train is already full, they do not mind standing at the side and climbing on top for 100 over KM. My legs would have sore and some standing were holding their luggage. It is a fortunate that it was a Diesel train not an electric one which I do not think they are able to afford it for full electrification.
