The standard gauge tank locomotive KBE 80 of the Cologne-Bonn Railways (KBE) was a steam locomotive for mixed heavy duty and was built by Hanomag in 1929. The single item was in operation until 1961 and was then taken out of service and scrapped.

history

In 1929, the Cologne-Bonn Railways needed heavier and more powerful locomotives for increasing operations. They ordered the heaviest 1'D1 'tank locomotive from Hanomag at the time. The locomotive should be able to move trains in the Wesseling area on gradients of up to 25 ‰.

The locomotive was powerful, had very good running characteristics and was used for passenger and freight train operations. The KBE railroad workers called the machine Jumbo . The machine was not popular with stokers, it consumed a lot of coal and was a poor steam maker. After the success of the locomotive 80 , the KBE relied more and more on locomotives with this wheel arrangement, but vehicles that were delivered later came from Krupp .

With the procurement of diesel locomotives, it gradually became superfluous, was in operation until 1961 and was then retired and scrapped.

construction

The locomotive was a Oberflächenvorwärmer of Knorr equipped. The minimum curve radius to be driven through was 140 m. The locomotive was equipped with fittings that corresponded to the standard of the Deutsche Reichsbahn . The Coale type safety valves and the tilting grate were also new for KBE .

The very large and powerful boiler rested on a bar frame that was constructed with a sheet metal thickness of 100 mm. Originally the locomotive had a Hanomag type feed water preheater with a Nielebock-Knorr type piston feed pump . The preheater was unsatisfactory and the KBE replaced it with a second jet pump .

The running gear of the locomotive was implemented at the front and rear with a drawbar frame of the modified Krauss-Helmholtz design . The side stop on the locomotive was ± 125 mm. The locomotive weight was distributed from the first and fourth coupling axles to the running axles using long balancing levers with a corresponding center-to-center distance so that the driving axles had an axle load of approx. 19 t and the running axles approx. The Heusinger control worked on piston valves with Knorr pressure equalizers . The air suction valve was fastened behind the chimney on the smoke chamber , it opened into the wet steam valve of the superheater box.

The KBE 80 had a pneumatic sand spreader with eight sand downpipes per engine side as well as a spacious and closed driver's cab. Around 1950 the locomotive was also equipped with smoke deflectors.
