The Sächsische IT were double-coupled tank locomotives of the Royal Saxon State Railways for mixed service, which came from the Chemnitz-Würschnitzer Railway Company , the Niedererzgebirgische Staatseisenbahn and the Greiz-Brunner Railway Company .
history
Hartmann built the first two locomotives in 1857/1858 for the account of the Chemnitz-Würschnitzer railway company, which was operated by the state railway and which it also took over in 1882. They were named WÜRSCHNITZ and LUGAU . The Niedererzgebirgische Staatseisenbahn acquired two more locomotives in 1858, which were named GÖSSNITZ and SCHÖNBÖRNCHEN and were used on the Glauchau – Gößnitz section .
The Greiz-Brunner Eisenbahn-Gesellschaft had two more copies built in 1865 with the names GREIZ and BRUNN , which differed in some details from the original IT. With identical main dimensions, they received a more modern boiler, which was characterized in particular by the steam dome built further to the front and a slightly higher nominal pressure of 7 atmospheres .
At the Royal Saxon State Railways, the locomotives used on the Niedererzgebirgische Staatseisenbahn were given operating numbers 86 and 87, those of the Chemnitz-Würschnitzer Eisenbahn numbers 88 and 89. They were listed as class HI and from 1876 as HIT . The locomotives of the Greiz-Brunner Railway arrived in 1876 in the stock of the state railway, where they received the car numbers 637 and 638. After the Leipzig-Dresden Railway Company had come into state ownership in 1878, the older locomotives were on their 1878 großenhain-priestewitz railway used . Later the 637 and 638 also got there.
The decommissioning of the machines began in 1885 with the number 86. In 1892 only the 87 and 88 of the older locomotives were given the new numbers 1692 and 1691, the newer ones became 1693 and 1694. When the new class designation IT was introduced in 1896, only received nor the two locomotives from 1865 this one for sure. The last to be retired was the number 1694 in 1905.
technical features
The locomotives had a semicircular standing boiler, a steam dome with a spring balance safety valve, horizontal external cylinders, an internal Stephenson control and an internal fork frame. The older locomotives did not get a closed driver's cab until 1865 , those of the Greiz-Brunner Bahn had it when they were delivered. They later received a steam slide brake and a sandpit on the boiler behind the cathedral. Before that, like the others, they only had a spindle handbrake.
