Locomotiva T28 este noua piesa din colectie sosita dupa Mos Craciun si cu mare intarziere dupa Anul nou. Locomotiva foarte diferita de cele pe care le am. Functiona atat pe linie normala cat si cu cremaliera. Mai multe date se afla in WIKIPEDIA:
A gear locomotives whose cogwheel drive system was designed for driving on tracks with racks was the 97-401. She came with the Prussian class T 28 to the Deutsche Reichsbahn in 1920. in 1925, she was classified as 97 401 in their numbering plan. After a stopover at the Eutin-Lübeck railway company (SSR) was the locomotive of the Deutsche Reichsbahn of the GDR and was given the operating number 93 6576.
History
The Prussian State Railways were no longer satisfied with the performance of the previously used T 26 locomotives. Also the traffic requirements were increased from the end of the 1910s. In addition to a higher tractive power, also an speed acceptable for passenger transport was requested.
The prototype by Borsig factory number 10781 was delivered in 1921 as Erfurt 9101. In spring 1922, sea trials were Ilmenau ââŹâ Schleusingen, Boppard Kastellaun and the Rübeland railway on the routes. It noted that the locomotives of the animal class of the Halberstadt-Blankenburg reached the achievements of the cogwheel locomotive in pure adhesion operation railway, as well as the class of 95 or even surpassed.
The T 28 was then used in the normal operating service on the route of Linz soaps in the Westerwald. Since the operation of the route could be ensured also by T 16.1 (DRG class 94.5-17) locomotives, 1929 was the sale of the locomotive at the Eutin Lübecker Eisenbahn-Gesellschaft (ELE). Where you removed the cogwheel drive and the locomotive was awarded the number 17 in understudy. About the Berlin Erich scrap at the end of the locomotive was in 1938 as number 59 (ab 1940-1-203) to the Brandenburg city railway (BStB). The locomotive was used in heavy freight train operation. Compared to the new locomotives with paragraphs 51 to 53, it was inferior this in performance and consumption of coal. With the acquisition of the Brandenburg city railway by the Deutsche Reichsbahn, the locomotive was given the running number 93 6576. 1955 the inefficient locomotive was retired and scrapped.
Constructive characteristics
The locomotive bar frame had a 80 mm thick. The riveted boiler consisted of two shots. The boiler situation was relatively high with 3000 mm. The Firebox with a 1.43 m wide grate area was executed in the Belpaire type. The steam dome was located on the first boiler. The sandbox was the second boiler.
The dome Wheelsets were supported by springs below the axle and the wheels of the axle to the frame. The first and the third axle were fixed to the frame. The fourth axis had a displacement of page of 16 mm. Since the wheels for the rack railway between the wheels of the dome were arranged, the Achsstände have been designed differently. The front and the rear shaft axis was executed with a page displacement of 100 mm as Bissel axle.
The engine was carried out as cylinder compound steam engine. The cylinders were arranged outside horizontally. The superheated and wet steam cylinders were arranged in a cast iron block on each side respectively. The underhead superheated steam cylinders were working on the second coupled axle and could operate in pure friction operation as a twin machine. The overhead wet steam engine worked on connecting rods and crank pulleys on the cogwheel drive. The gears were between the first and second, and the second and third dome wheel set.
The Hay singer control was outside. The reverse of the two engines were common. The locomotive had a single chamber air brake of type of Knorr with auxiliary brake. The brake worked on the second and third coupled axle. In addition, the steep route operation existed a Riggenbach counter-pressure brake. To do so, the machine had via a hand-operated grooves band brake for the cogwheel drive, as well as a throw lever parking brake.
The water was stored in two side water tanks, as well as behind the driver's cab. The coal box was also behind the driver's cab.
