Bavarian E I
Encyclopedia
The Bavarian Class E I steam locomotives operated by the Royal Bavarian State Railways
encompassed four different variants of saturated steam, goods train locomotive with a 2-8-0
wheel arrangement.
. In addition the outside Walschaerts (Heusinger) valve gear had very short connecting rods on the engines delivered to Bavaria

The vehicles were coupled with Bavarian Class bay 2'2' T 18 tenders. Later they were equipped with Class 3 T 12.3 tenders from the Bavarian B XI
's.
. The advantage of this locomotive variant was that the double cylinder was very short as a result of the tandem construction. That said, the engine did not perform especially well, so that the two units were converted into locomotives with a conventional cylinder arrangement.
with the numbers 56 312 - 56 353. It was the same as the Sondermann variant after the conversion of the latter. These locomotives could haul a train of 820 tons at a speed of 50 km/h and even attained a speed of 40 km/h with a 1,390 ton train. On a line with a 0.5% incline they could manage a 845 ton train at 25 km/h.
were goods train steam locomotives imported from the USA for testing purposes.
The two machines were the first in Germany
to have a bar frame, which had been standard in the USA virtually from the beginning and which had been developed from the wooden beam frames of the early locomotives.
Like the two S 2/5
express train locomotives also imported from Baldwin a year later these engines were equipped with a four-cylinder Vauclain compound
engine, on which the high-pressure and low-pressure cylinders were located directly one above the other and worked on the same connecting rods. Apart from the bar frame, this type of drive did not catch on in Bavaria

Royal Bavarian State Railways
As a nation-state, Germany did not come into being until the creation of the German Empire in 1871 from the various German-speaking states such as Prussia, Bavaria, Saxony, Baden and Württemberg. By then each of the major states had formed its own state railway and these continued to remain...

2-8-0
Under the Whyte notation for the classification of steam locomotives, 2-8-0 represents the wheel arrangement of two leading wheels on one axle , eight powered and coupled driving wheels on four axles, and no trailing wheels...
wheel arrangement.
Standard variant, older type
The first series of E I's was built by Krauss in 12 examples. The cylinders were positioned in front of the carrying axle and drove the first coupled axle. The carrying and driving axles were linked together in a Krauss-Helmholtz bogieKrauss-Helmholtz bogie
A Krauss-Helmholtz bogie is a mechanism used on a steam locomotive, where a carrying axle is connected to a coupled axle via a lever such that when the carrying axle swings to the side on going round a curve, it causes the coupled axle to move sideways in the opposite direction...

Sondermann Variant
The second E I series delivered to the Royal Bavarian State Railways was the Sondermann Variant built from 1896. It had two overlapping cylinders that formed a combined double slide valve (Doppelschieber). The carrying axle and the first driving axle were housed in a Krauss-Helmholtz bogieKrauss-Helmholtz bogie
