With tender subsidy a modern narrow-gauge running bogie will be developed, that could be used not only at locomotives, but at motor-coaches as well. Because of the good “off-road skill” the bogie can provide a high passenger comfort even on bad conditioned railway track. The minimum unsprung mass spares the track. With the appearance of the narrow-gauge bogie the technical barrier disappears from the development of locomotives and motor-coaches (producing new or reconstruction) and also vanishes the obstacle on the vehicle side of the ecotourism. Furthermore those Narrow-gauge Railways, that have appropriate touristic destinations could rocket their level of services which can lead further tourists, passengers.
