The sight of the coal fired boiler of the steam locomotive with its door open is a rare sight. The loco staff opens it before the journey to top it up with coal. It is the moment when the lid of the boiler is opened, that the sight of the yellow orange dancing flames make you realise the power they hold and will soon unleash to make this loco pull the coaches of the narrow gauge Darjeeling Himalayan Railway.
