Some parts of the two locomotives are similar to the Prussian T 3 . In contrast to this, however, the T 33 had a Heusinger control .
Originally they were numbered 51 and 52. After the establishment of the Reichsbahn , the machines were taken over. There they were given the numbers 99 031 and 99 032. The machines carried 3.0 m³ of water and 1.0 tons of coal .

Except for the length and the larger service weight, the five vehicles of the second series did not differ from the two of the first series. They were numbered 53-57
After the establishment of the Reichsbahn , the machines were taken over. There they were given the numbers 99 041–99 045 . Three locomotives came to the Neustadt depot of the RBD Ludwigshafen and were there on the local line Speyer-Neustadt in use, 1955 to 1957 they were retired.
The machines carried 3.0 m³ of water and 1.0 tons of coal .

Some minor changes were made to the two vehicles of the third (No. 58-59) and the four of the fourth series (No. 60-63). So they had a larger grate, but a smaller evaporation heating surface and the air tanks were now under the driver's cab . The third series was delivered in 1912, the fourth in 1914.
After the establishment of the Reichsbahn , the machines were taken over. There they were given the numbers 99 051–99 052 and 99 061–99 063 . The Erfurt 63 , with slightly larger storage containers, was sold in 1924 and was not given a Reichsbahn number. All locomotives were retired in 1935.
The machines carried 3.0 m³ of water and 1.0 tons of coal .
