The BGV 25 was a narrow gauge - steam locomotives of Borzsavölgyi Gazdasági Vasút (BGV; German: Borzsatalbahn ), which after 1918 by the CSD was acquired, where the term U 44.0 received.
history
The U 44.0 series machine was one of several four-axle, uniform narrow-gauge tender locomotives that Maffei in Munich delivered to various works railways in 1913 for various tasks in the period before the First World War . A locomotive with four driven axles was the only option for handling larger loads so as not to exceed the permissible axle load. The manufacturer used Klien-Lindner hollow axles to ensure the curve mobility with the existing curve radii . In addition to the Borzsatalbahn locomotive , other locomotives were used on various forest railways.
The locomotive used by the ČSD was in use on its main line from 1913 to 1927 and from 1930 to the 1950s. In the meantime, she was in use on the former Uzhhorod - Radwanka forest railway from 1927 to 1930 .
After being used by the ČSD , it was adopted by the MÁV as the MÁV series 493.0 . A photo shows a 1956 locomotive on a Romanian forest railway .
A locomotive from the same manufacturer from the same year of construction with a similar manufacturer's car number has been preserved in the legacies of the Usora Valley Railway . The machine is said to be in Blatnica today .
