The DRB Class 01.10 belongs to the type 2'C1' h3. It has 2 successive running axles united in a bogie, independent of the main frame, and 1 running axle independent of the main frame. The steam type is superheated steam and the machines have 2 or 3 cylinders.
The steam locomotive DRB class 01.10 is a further development of the steam locomotives of the Deutsche Reichsbahn.
For its network of high-speed D and FD trains, the Deutsche Reichsban needed steam locomotives with a maximum speed of 150 km/h. Trains with 550 tons had to be transported on the plain at 120 km/h and 425 tons on a gradient of 4 per mille at 100 km/h.

The existing locomotives of the Class 01 and Class 03 were only permitted to travel at a maximum speed of 130 km/h, but were designed for a speed of 140 km/h. A higher speed could not be guaranteed due to the strong twitching movements caused by the two-cylinder engine. In view of better starting characteristics, it was decided to purchase steam locomotives with three-cylinder engines and simple steam expansion.
The vehicles were equipped with a streamlined fairing that was lowered 400 millimetres above the top edge of the rails. This should contribute to reducing the running resistance. As a result, the tractive power could be increased by 48% at speeds of 140 km/h, as shown in tests with the class 03. Due to a poorer steam supply to the three-cylinder engines, the additional power at higher speeds was partially eaten up.
A requirement of 400 locomotives was calculated. In 1939, 204 locomotives were ordered from all large locomotive factories in Germany. Only 55 locomotives were delivered due to the war. They all came from the Schwarzkopff company.
The following depots received the DRB class 01.10:
Leipzig West Main Station,
Berlin Anhalter Bahnhof,
Halle (Saale) Central Station
Hamburg-Altona,
Hanover East, Bebra, Erfurt P,
Dresden Old Town,
Frankfurt (Oder) Pbf,
Würzburg,
Munich and
the Grunewald Experimental Office.
Some of the locomotives were transferred to Wroclaw and Katowice during the war. In 1944 all locomotives were transferred to West Germany.
After the end of the war the vehicles were in a desolate state. In many cases parts of the streamlined fairing were missing and the boilers showed the first signs of fatigue. On 20 June 1945 a decision was taken to retire the entire series. The previous mileage of the machines amounted to 500,000 kilometres. Due to the prevailing lack of locomotives, this series was chosen again. Some locomotives with minor defects or damage were temporarily repaired.
A large part of the DRB Class 01.10 series remained parked until 1949. In the same year it was decided that all locomotives would be refurbished. Except for the steam locomotive 01 1067, the streamline fairing was completely removed and Witte wind deflectors were fitted. The outward appearance was rather unusual for German locomotives. This was due to the chunky looking surface preheater, which remained sitting crosswise in front of the chimney. Therefore the smokebox door above the middle was cut off straight. Only two locomotives had been equipped with the round smokebox door.
The problematic boilers from St 47 K were replaced between 1953 and 1956 by new high performance boilers with combustion chamber and a mixing preheater system type Heinl at the Braunschweig repair works. The new boilers had a larger proportion of radiant heating surface and smaller grate and total evaporation heating surface. Nevertheless, the evaporation capacity was about 10% higher than with the old building boilers. For the locomotives with oil main firing, steam consumption of up to 5.8kg/PSih was thus possible.
The 01 1100 was equipped with an oil-fired main boiler in 1956. The output could thus be significantly increased. Furthermore, the oil firing system could be controlled more elastically and thus be better adapted to the operating conditions. The vehicles were thus more economical. In addition, the work of the heater could be made easier, as now no more coal had to be shovelled. The fuel supply was regulated via a slide valve. The heater was now able to support the locomotive driver on both tracks. The heavy fuel oil was burned (bunker-C). In 1957 it was decided that a further 33 locomotives of this series would be equipped with oil firing.
In 1968 the coal-fired locomotives were given the class designation 011, the oil-fired locomotives the 012. The steam locomotives were used on all important main routes, e.g. Hamburg-Würzburg or Hamburg-Hamm. Most recently they were found on the Hamburg-Westerland and Rheine-Norddeich lines.
On 31 May 1975 the last vehicles of the series were used for the last time as scheduled by the Bw Rheine and connected and sympathized with railway enthusiasts.
