With tender subsidy a modern narrow-gauge motorized 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 UHFV bogie can provide a high passenger comfort even on bad conditioned railway track. The minimum unsprung mass spares the track and the electric traction motor makes the recuperation of the battery possible during down the hill using breaks. The UHFV bogie can be applied as a running-gear to diesel-electric, hybrid or only battery run vehicle. 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.
