Locomotives of the Hanover State Railway
The Royal Hanover State Railways owned various types of locomotives from different manufacturers until 1867 , although from 1850 the Hanover-based company Egestorff supplied most of the machines.
First locomotives
The first suppliers of locomotives for the Hannöversche Staatsbahn were Sharp (Manchester) with locomotives 1 to 4 in August and September 1843 and Stephenson (Newcastle) in December 1843 with locomotives 5 and 6. These machines had one driving and two running axles and were all of them retired by May 1862 and replaced by more modern machines. The three locomotives 7, 10 and 11 of the Zorge machine factory in Braunschweig were only in service between 1844 and 1857. The two locomotives 19 and 20 from Maffei (Munich) - delivered in September 1846 - also failed and were shut down in the summer of 1856. The first B-couplers came from Norris (Philadelphia) in 1846 as locomotives 15 and 16 and in April 1847 as 31 and 32 from Maffei, but were also retired early (both types by August 1855).

Locomotive types up to 1867
The different types of locomotives had no special names. In the holdings of the Hanover State Railroad, they were simply given with an operating number. If a locomotive was taken out of service, its operating number was reassigned. Names for locomotives were not common on the Hanover State Railroad.
A driving axle
42 inches (1,066 mm) = In June and December 1846 and February 1847, numbers 14, 25 and 28 were the first locomotives from Egestorff from Hanover. These machines had a driving axle that was 42 inches in diameter. By the end of 1847 another four machines of this type came to the Hanover State Railroad. These seven locomotives were converted into C-couplers in 1864/65.
The first of these locomotives was handed over on June 14, 1846. It was the first locomotive ever produced by Egestorff. As early as June 11, 1846, it is said to have run between Hanover and Celle as a trial and opened the Hildesheim - Lehrte line on June 12, 1846. It is said to have been named "Ernst August" after the King of Hanover. The railway company simply ran it as the number 14 locomotive. It was in use until 1872. During this time she covered more than 1,000 miles (1 land mile at 7,532.5 meters ), which was praised at the time. The locomotive had a steam boiler at the front , a raised fire box , inclined cylinders and a Stephenson swing control. The vehicle was equipped with a Schlepptender provided of the type T 3. 5
60 inches (1,524 mm) = Borsig delivered locomotives 12 and 13 (one driving axle) in November 1845, which were the oldest machines still in operation at the end of 1867. In 1846 another four Borsig machines followed. At the same time, the Hannöversche Staatsbahn had purchased machines with one driving and two running axles with a driving wheel diameter of 60 inches (1.524 m) from Sharp in Manchester from September 1846 (seven locomotives: numbers 17, 18, 26, 27, 29, 30 and 40) and from October 1847 by Keßler in Karlsruhe (four locomotives: numbers 36 - 39). After machine 43 from October 1847, Egestorff delivered five more locomotives in Hanover with the numbers 49, 62, 63, 66 and most recently in January 1852 the number 76. All machines were still in operation on December 31, 1867.
84 inches (2,124 mm) = In the course of time, the vehicles of type 1B proved to be no longer powerful enough for the ever increasing demand for express trains. Type 2A vehicles were purchased as a replacement. They were used for this purpose until 1870, when the trains became too heavy for the vehicles. Some vehicles still ran into the 1890s. The Kirchweger condensation device was particularly noticeable on the machines. They were equipped with type 3 T 6 / 3.5 tenders .
Supplied by Wöhlert in Berlin 19 units (111 to 120 from October 1853 to January 1854, from 130 to 137 in July 1855 to 145 in December 1855) and later by Egestorff in Hannover 14 units (175 to 182 from July 1857 to December 1857 and 191 - 196 from August 1859 to February 1860). Internally, these machines were called "Courier locomotives" because the faster lighter Courier trains attracted to the 1867 timetable moderate average of 7.706 miles per hour (57.2 km / h) drove while fast trains 6.691 miles (49.64 km / h) and the passenger trains traveled 5.877 miles an hour (43.6 km / h).
Two driving axes
54 inches (1,372 mm) = Between October 1847 and April 1848 the Hannöversche Staatsbahn put a total of 20 machines of this type into service. Six each were delivered by Borsig, Sharp and Cockerill and two by Keßler. Except for the two Borsig machines 44 and 46 (decommissioned December 1867), the other 18 were still in stock at the end of 1867.
60 inches (1,524 mm) = The breakthrough for Egestorff came with locomotive 67 in July 1849. The B-coupler with 60 inch drive wheels became the most built locomotive of the Hanover State Railways. From July 1849 to December 1861 the company delivered a total of 103 locomotives of this type. They were sold under the company numbers 1 - 11, 15, 16, 19, 20, 31, 32 (all second numbering), 67 - 72, 75, 77 - 100, 107 - 110, 121 - 129, 138 - 144, 146, 147, 154-174, 187-190 and 200-208 included in the inventory. All machines were still in operation on December 31, 1867.
They were equipped with a front steam dome that had a Kirchwegian weight safety valve . Some of these machines were taken over by other railways of the Prussian State Railways .
The vehicles were coupled with type 3 T 5 and 3 T 7 tenders .
66 inches (1,676 mm) = In October 1851 Wilson in Leeds delivered the first two B-couplers with a 66 inch drive wheel diameter. 19 more locomotives of this type, built by Henschel in Kassel, followed in January 1858 . In November 1865 Egestorff added another 9 machines to the stock.
Three driving axes
54 inches (1,372 mm) = In January 1853, the first 7 Wilson locomotives came into service in Leeds. In January 1856, Egestorff then built 11 locomotives as C-couplers. When Hanover was already Prussian, the Hanover State Railroad then purchased four locomotives from Schwarzkopff in Berlin, which were given the highest operating numbers in the Hanover State Railroad's inventory before the Prussian takeover of management with the numbers 237 to 240.
57 inches (1,448 mm) = From October 1863 to March 1866, Egestorff supplied a total of 7 C-couplers (C wheel arrangement) with this slightly larger drive wheel diameter.
Conversions from 42 " = This concerned the seven A-couplers with 42" drive wheel diameter, which had been delivered since 1846, to which the aforementioned locomotive 14 ("Ernst August") also belonged. In 1864 and 1965 they were converted into a C-coupler. With their small drive wheel diameter, these machines were apparently no longer suitable for the faster route operation.
Stock taken over by Prussia in December 1867
In December 1867, the Hanover State Railroad had 240 locomotives in its portfolio, numbered from 1 to 240. The numbers of the 17 previously decommissioned locomotives (1 to 11, 15, 16, 19, 20, 31 and 32) had been reassigned.
Suppliers of the locomotives in operation were Egestorff in Hanover with 152 units, Borsig in Berlin with twelve, Sharp in Manchester with 13, Keßler in Karlsruhe with six, Wöhlert in Berlin with 13, Cockerill in Seraing (Belgium) with six, Wilson in Leeds at nine, Henschel in Kassel at 19 and now in 1867 Schwarzkopff in Berlin at four.
The oldest locomotives in operation were locomotives 12 and 13 from Borsig, which were put into service in November 1845.

The vehicles of this type had a long fire box and a raised, rectangular rear boiler ceiling. The steam dome had a Wöhler safety valve and the back boiler a Salter safety valve . Later on, the boiler pressure was converted from 98.1 kN / cm² to 117.7 kN / cm². All vehicles that could also be used to pull freight trains on flat routes were also taken over by other railways of the Prussian State Railways .
The vehicles were equipped with type 2 T 8.5 tenders .

In order to meet the increasing demand for locomotives, the Royal Hanoverian State Railways had more passenger locomotives built based on the express locomotive of the same design. They had an elevated Belpaire-style boiler above the second coupling axle. After taking over the Hanover State Railways, the Prussian State Railways classified all vehicles in the P 3.2 series .
The machines were equipped with type 2 T 8.5 tenders .
Type 1B
| Express passenger locomotive | |
|---|---|

The vehicles were the successors to the type 2A. All machines were later converted from 10 bar overpressure to 12 bar. 32 units were equipped with a Wöhler type safety valve, the rest of the Meggenhof type. The Prussian State Railways took over the vehicles in the P 3.1 series .
