The four-axle brigade locomotives of the Bulgarian state railways Balgarski Darschawni Schelesnizi (BDŽ) , which were used from 1920 in Bulgaria and here until around 1970 on numerous narrow-gauge railroads with a gauge of 600 mm, were designated as BDŽ series 400.60 . Most of the 93 numbered locomotives were decommissioned soon after the Second World War , a few were able to keep in operation until 1970, on industrial railways until 1973. According to the locomotive statistics of Josef Pospichal, four locomotives have been preserved.
history
All locomotives on the numerous narrow-gauge railroads in Bulgaria came from the stock of the German Army Field Railway . The locomotives initially continued to run under their name on the Heeresfeldbahn in Bulgaria, only from 1936 on they received their new designation, the BDŽ, starting with 401. In addition to these locomotives, two-axle and three-axle locomotives of the Heeresfeldbahn drove in Bulgaria, the four-axle locomotives were clearly in the number Outnumbered and lasted longer.
For the first time, Bulgaria received over 200 brigade locomotives for the routes in the country and Macedonia during the First World War . Since the locomotives of the German troops in Macedonia were added to this, it can be assumed that there were around 300 locomotives during that time. During the war there were numerous losses of vehicles and after 1918 several repatriations and relocations, so that ultimately 93 locomotives were counted among the BDŽ in peacetime.
The feature of the Bulgarian brigade locomotives was the use of a firebox, deviating from the standard equipment, to use inferior fuel. For this, the boiler had to be moved to the front and was no longer flush with the water tanks. The Kobel chimney was removed from them and they received a thin, long chimney with a fine dust filter . Add-on boards were added to increase the coal supply. It can be assumed that all brigade locomotives in Bulgaria had Klien-Lindner hollow axles , so that they could easily negotiate a minimum curve radius of up to 20 m. The chassis was red, the boiler black, the driver's cab and water tank green. There were also small red decorative lines on the edges.
The machines were very successful in Bulgaria and have been in use for over 50 years. In addition, many locomotives were operated with a brigade tender to increase their operating range, which increased their operating range by 500%. During their long service life, component swaps were often undertaken, so that in the end the boiler, chassis and frame numbers no longer matched. Many brigade locomotives were taken out of service after the Second World War due to line closures or gauge changes, but some remained in service until 1970. In industrial railways they stayed a little longer, until 1973. At the present time copies obtained is written by four; the most famous locomotive is the 479.60 , which is on display at the main station in Sofia , two locomotives, the 470.60 and the 486.60 are attributed to the Ruse Railway Museum , and one locomotive is said to have been preserved in Dupnitsa .
