The . No. 1 and 2 were meterspurige gear - steam locomotives the Zsakaroczvölgyi Iparvasut ( Industriebahn Žakarovce ) in the then upper Hungary .
history
The two locomotives were delivered in 1884 with the serial numbers 2052 and 2053 by the Esslingen machine factory.
After the ore line was shut down in 1899, the locomotives were no longer used. One made its way to Štrba in 1902 to the Lake Czorba rack railway in the High Tatras , where it was probably no longer used. In 1910, both vehicles were sold to Orenstein & Koppel's Vienna branch ; their whereabouts are unknown.
Similar locomotives based on the same construction plans were later manufactured by the Floridsdorf locomotive factory for the Csorbasee cog railway and the Achensee railway in Austria. They are still in operation on the Achenseebahn today.
technical features
As is often the case with gear steam locomotives, the two-cylinder wet steam engine worked on a countershaft. The centrally arranged gear axle also served to transmit power to the two normal drive axles for adhesion operation by means of coupling rods .
Three independent braking systems ensured safe operation on the gear train. The usual at Rack steam locomotives Riggenbach - counter-pressure brake served as inertia brake when going downhill. There was a grooved belt brake on the transmission, which served as an additional service brake to stop and secure the train. A grooved block brake acted on the brake gear. All three systems were in a position to hold an entire train on the steep stretch.
