Then a piercing siren sounds and in a flash the market transforms - the shoppers disappear and the stallholders whip away their produce. One moment you see the locals shopping for their vegetables and the next moment the vendors will scoop up their baskets and boxes and anything that lies over the track. The market comes to a standstill as all the vendors hold on to the poles supporting their awnings to make way for the train to pass. It is such a tight squeeze that the train travelling at about 15mph almost touches the fruits, vegetables and everything else at the marketplace as it passes through.
