The BDŽ No. 1.76 to 10.76. Were steam locomotives of the Bulgarian State Railways BDŽ , for the operation of the in Bosnian gauge running narrow gauge railways from the company Rheinmetall were built and were used after the replacement of the narrow-gauge railways for some years in private companies. The locomotives emerged from the JDŽ 72 of the Yugoslav narrow-gauge railways and were considered to be the first in-house production machines in this gauge. Two locomotives of this series have been preserved to this day.
history
The first locomotives for the operation of the Bulgarian narrow-gauge railways in Bosnian gauge came from Serbia . When the narrow-gauge line in Červen Brjag opened in 1918, there were no locomotives of its own. Today it is no longer possible to determine exactly how many locomotives ran on this route before the company's own machines were delivered. However, the opening of the first sections of the Rhodope Railway was also taken over by these small locomotives. The locomotives soon proved to be too small and inefficient, so that they were replaced by the 500 series from 1927 . Only three locomotives remained in Septemwri , which probably took over the passenger train service until the railcars arrived, as well as the shunting service . The rest of the machines were based in Červen Brjag . Due to the increasing total traffic, the vehicles were soon overloaded on this route, so that the machines of the 500 series took over the freight traffic on this line from then on. Passenger traffic continued to be carried out by class 1-10 locomotives .
It was only when the new 75 series replaced all steam locomotives and railcars on the Rhodope Railway that the last hour of the small steam locomotives had struck. The class 82 railcars were moved to Červen Brjag , but could not completely replace the steam locomotives there. Only the 600 series locomotives, which were also moved to Červen Brjag , completely replaced the 1–10 series locomotives , so that in 1967 all the 1–10 series locomotives were retired. Locomotive 1 was then handed over to Septemvri, where it performed various services until 1970. Then the locomotive was moved to the Ruse Railway Museum , after 2002 the locomotive came back to Septemvri, where it is waiting to be reconditioned. It is not known whether it is operational or just external. The last locomotive 10.76 has also been preserved; the locomotive was after its retirement in 1966 in Septemvri from the same year until 1970 working locomotive in the Raslog paper mill . After that, the locomotive was a museum locomotive in Bansko until 1998 and is now erected as a memorial at Plovdiv Central Station . In February 2018 the locomotive will be in the Septemvri depot, and the main train station there is undergoing extensive structural renovation.
technical description
Today there is little well-founded technical information about the origin of the locomotives and their technical descriptions. Its origin is described as a derivative of the JDŽ 72 , another so far little-known locomotive, some of which opened the narrow-gauge railway in Červen Brjag before the arrival of the company's own locomotives . These machines were proven locomotives on the Serbian narrow-gauge railways, so it was decided to replicate them as the first locomotives on the Bulgarian narrow-gauge railways. Besides the technical data, only the serial numbers 429 to 438 are known from the literature .
In terms of their dimensions, they were somewhat larger than the well-known U series of the same design. Otherwise the locomotives were designed as two-cylinder compound locomotives . With their evaporation heating surface, the locomotives were generously sized and only slightly below those of the two series 500 locomotives built by BMAG .
