What you see in this video is known as a RORO service. RORO is short for "Roll On Roll Off". In this service provided to truckers by Indian Railways, loaded trucks are directly carried by railway wagons to their destination. This section of Indian Railways known as Konkan Railways passes throughone of the toughest tough terrains of en.wikipedia.org/wiki/Indiandia . There is a highway passing through same route. Truck drivers find it extremely difficult to drive loaded trucks through en.wikipedia.org/wiki/Ghats , undulating surfaces, narrow roads and poor road and weather conditions. The Indian Railways came with concept of RORO, where loaded trucks are moved on wagons and are travelled by train. This has helped in saving of fuels, decrease in wear and tear of lorries (trucks), relief to drivers of driving in extreme conditions, can reach faster to destination. This also helps in decongestion of roads and lowering of pollution. This concept has been beneficial for both truck operators and the Railways.
