Companion to the DHR film, featured in this DVD are 18 selected Indian narrow gauge lines, and more than 64 identified locomotives of various classes, all on film shot between 1970 and 1985. The majority of the lines are sub-metre gauge, and there some wonderful shots of grossly overladen trains in the countryside. A map before every section tells you where you are, which is an excellent idea. If you like the narrow gauge you will like this.
