The first series of the EI was produced by Krauss in 12 copies. The cylinders were in front of the running axle and drove the first coupling axle. The barrel and driving axle were combined in a Kraus-Helmholtz bogie . In addition, the external Heusinger control with very short drive rods was a variant limited to Bavaria .
The vehicles were traveling with a Tender of the type bay 2'2 'T 18 equipped. Later they received the tender type 3 T 12.3 of the Bavarian B XI .

| other technical data such as newer standard design; slightly different weights | |
The second series of the EI of the Royal Bavarian State Railroad was built as the Sondermann type from 1896. It had two cylinders nested inside each other, which shared a double slide. The running axle and the first driving axle were in a Krauss-Helmholtz bogie . The advantage of this locomotive was that the double cylinders were quite short due to the tandem construction. However, the locomotive did not prove itself particularly well, so the two locomotives were converted into vehicles with two conventional cylinders .

The third series of the EI of the Royal Bavarian State Railroad represented the final form of this series. A total of 48 vehicles were produced and 42 were taken over by the Reichsbahn with the numbers 56 312 - 56 353. They resembled the vehicles of the Sondermann type after the conversion. At a speed of 50 km / h, the locomotives could pull a train of 820 tons. With a 1,390-ton train they could still reach 40 km / h. On a route with a 0.5% gradient, they reached 25 km / h with an 845-ton train.
A machine came after the First World War to the PKP and was out there as Tr101. In the second list of PKP machines from 1936, which is still available to research today, it no longer appears.

The vehicles of the type EI of the Royal Bavarian State Railways built by Baldwin were steam freight locomotives imported from the USA on a trial basis .
The two machines were the first in Germany to have a bar frame, which had been common practice in the USA from the very beginning and developed from the wooden beam frames of the early locomotives.
Like the two express train locomotives of the class S 2/5 , also imported by Baldwin a year later , the locomotives were equipped with a four-cylinder compound drive of the Vauclain type, in which one high-pressure and one low-pressure cylinder were arranged directly on top of each other and operated on a common connecting rod. Unlike the bar frame, however, this type of engine did not catch on in Bavaria.
The locomotives were a Tender equipped to type 2'2 'T 18.1.
