Disposition4 preserved, 5 sold to Argentina, 1 scrapped

The locomotives were built and delivered by the Romanian plant "23 August" (now FAUR) - Bucharest under technical conditions of BDZ. Maximum interchangeability of aggregates, assemblies and parts with the class 76 machines, built in the same plant, was pursued. The main differences with them are:

All class 77 locomotives are assigned to the Septemvri depot. This fully satisfied the needs for narrow-track locomotives at the then volume of traffic. Since the beginning of the 1990s there has been a drastic decline in transport. Then almost half of the locomotive fleet remained idle. A good way out of this situation was in 1996 the sale of 5 locomotives of the series. On March 20, 1996, the narrow gauge engines were loaded onto normal track wagons and transported to the port of Bourgas and loaded onto a ship with which they were transported to Argentina. There they were sold to serve a narrow-gauge railroad between the coal mines in the Rio Turbio village and the Rio Galegos port, about 200km in the Santa Cruz area of Patagonia. One of the remaining 5 locomotives was scrapped and the rest continue to work on the Septemvri–Dobrinishte narrow-gauge line.

<span class="mw-page-title-main">Steam locomotive</span> Railway locomotive that produces its pulling power through a steam engine

A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material to heat water in the locomotive's boiler to the point when it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels.

The Leek and Manifold Valley Light Railway (L&MVLR) was a narrow gauge railway in Staffordshire, England that operated between 1904 and 1934. The line mainly carried milk from dairies in the region, acting as a feeder to the 4 ft 8+12 instandard gauge system. It also provided passenger services to the small villages and beauty spots along its route. The line was built to a 2 ft 6 in narrow gauge and to the light rail standards provided by the Light Railways Act 1896 to reduce construction costs.

BDŽ class 75 Type of train

The BDŽ class 75 is a series of Bulgarian narrow-gauge diesel-hydraulic locomotives.

After 1973 the acquisition of additional high-speed diesel locomotives was considered to complement the BDZ park for the Septemvri - Dobrinishte line and especially for the replacement of the steam tram along the line Cherven Bryag - Oryahovo. The acquisition of class 75 locomotives failed for a number of reasons. Thus a construction and supply contract was signed with the Romanian plant "23 August" - Bucharest. The locomotives were built to the technical conditions of BDZ, reflecting the experience of the already 10 years of operation of the class 75 locomotives.
