The 99.19 series describes a five-axle meter-gauge locomotive series of the Deutsche Reichsbahn . The design was essentially based on the 99.64-65 / 67-71 series for 750 mm narrow gauge. The four locomotives were initially used exclusively on the Nagold – Altensteig narrow-gauge railway ; it was not until the Second World War that two vehicles were also used on other routes. One locomotive - the 99 193 - has been preserved.
history
As early as the First World War , the Royal Württemberg State Railways wanted to replace the used and technically complex locomotives of the series Ts 3 and Ts 4 with 1000 mm gauge for the narrow-gauge railway Nagold – Altensteig. However, due to the World War and the poor economic situation afterwards, this was initially not possible.
In the early 1920s, the Reichsbahndirektion Stuttgart received five brand-new locomotives of the 99.67-71 series, an almost unchanged replica of the 99.64-65 series (former Saxon class VI K ), with 750 mm gauge for the Bottwartalbahn . Since the vehicles proved their worth, four locomotives with the serial numbers 4181 to 4184 were built for the Nagold – Altensteig narrow-gauge railway in 1927 by the Esslingen machine factory, which were largely similar to the 99.64–65 / 67–71 series. They were given road numbers 99 191 to 194 and together cost around 275,000 Reichsmarks. In April 1927 the first vehicle was put into service by the Deutsche Reichsbahn.
Use and whereabouts
Initially, the vehicles only ran on the Nagold - Altensteig narrow-gauge railway, where they displaced the 99.12 (formerly Ts 3) and 99.17 (formerly Ts 4) series. The steam locomotives were used from the Altensteig locomotive station of the Freudenstadt depot .
In 1944 two machines had to be handed in. The 99 191 was relocated to the Reichsbahndirektion Erfurt at the end of May 1944 , where it was used on the narrow-gauge Eisfeld – Schönbrunn railway . The 99 194 most likely made it to the Balkans during the war, where it operated on a narrow-gauge network near Belišće .
After the war, the 99 192 and 99 193 remained in the French occupation zone , the 99 191 in the Soviet occupation zone and the 99 194 in Yugoslavia.
The 99 194 was probably shut down in the 1950s due to boiler damage and then scrapped; it had not yet been given a new number.
- German Reichsbahn
The 99 191 remained on the narrow-gauge railway Eisfeld – Schönbrunn after the end of the war. With the delivery of two new locomotives of the 99.23–24 series in the spring of 1955, the locomotive was relocated to Gera. There it was used on the Gera-Pforten-Wuitz-Mumsdorf narrow-gauge railway . There it carried the main load of the operation with the two locomotives of the 99.591 series . Here it was given a wooden beam on the buffer beam at both ends for shunting standard gauge wagons on the three-rail tracks in the Wuitz-Mumsdorf station. After the closure of the last section in early 1970, the 99 191 was z-laid on June 11, 1970. Since a sale to a museum railway abroad failed, the vehicle was scrapped in 1975 at the Görlitz Reichsbahn repair shop.

The 99 192 and 99 193 were defective at the end of the war and were refurbished by the end of 1945 / beginning of 1946. From then on they took over the train service alone on the narrow-gauge railway Nagold - Altensteig, a replacement locomotive that had meanwhile been borrowed from the Härtsfeldbahn was returned. Since at the end of 1949 part of the passenger traffic was transferred to the bus, from then on only one machine was used a day.
From the summer of 1956, both locomotives were only available as a reserve after the V 29 952 diesel locomotive had been moved to Altensteig from the Regensburg - Wörth Walhalla Railway . The 99 192 was taken out of service on May 15, 1959 and from now on served as a spare parts dispenser. Due to the increased road traffic, the 99 193 received white and red warning signs on the right side of the locomotive, as the route ran for several kilometers directly next to the road. On November 30, 1967, the 99 193 was taken out of service, a list as a memorial in Altensteig failed. Since 1969 it has been with the Blonay – Chamby museum railway in Switzerland.
technical features
The design was essentially based on the 99.64-65 / 67-71 series for 750 mm narrow gauge.
- Boiler and engine
The firebox was 1,386 mm wide and 1,544 mm long, it joined the 3245 mm long from a gunshot existing boiler barrel on. The fire box was made of copper, which was only replaced by a steel one on the 99 191 in the mid-1960s.
The superheated steam locomotive had a two-cylinder engine with a piston stroke of 400 mm and a diameter of 430 mm. The drive rod acted on the fourth axle of the five-coupler, the wheel diameter of which was 800 mm. The external Heusinger control was equipped with Kuhn loops for even steam distribution in both directions of travel .
- Frame and chassis
The riveted sheet metal inner frame was 18 mm thick, inside the frame cheeks there was a frame water tank with a capacity of around 0.66 m³.
According to the Gölsdorf principle, the first and fifth wheel sets could be laterally shifted by 30 mm and the third by 20 mm for the tight curve radii . In addition, the third axle had flanges that were ten millimeters less. The first and last axes were equipped with reset devices for better guidance.
In addition to the mandatory throw lever brake as a hand brake, the Westinghouse brake was also available. The air reservoir required for this was arranged across the front buffer beam. The 99 193 also received a suction air brake for its museum railroad use . A simple funnel coupling with suspension was used as the coupling . The 99 193 received central buffers with an underlying screw coupling according to French standards for operation on the Blonay – Chamby museum railway.
- Stocks
The riveted water tanks on the side each had a capacity of 2 m², the water tanks at the front were beveled, so that a better view to the front was achieved. Due to the wider frame, the frame water tank was larger, so that the machines could hold a total of 4.66 m² of water. The coal reserves were 2 t, but since the manufacturer was based on the drawing for the 99.64-65 / 67-71 series, the reserves were initially given as 2.5 t, although the 0.5 t compartment on the left-hand standing boiler side was not installed had been.
- Others
The locomotive lanterns were initially powered by kerosene, but the vehicles were not fitted with electrical lighting until the early 1930s.
