Bavarian B I
Encyclopedia
Bavarian B I engines were 2-4-0
steam locomotives of the Royal Bavarian State Railways
(Königlich Bayerische Staatsbahn).
The Class B I was developed in parallel with the Class A II
, but had a coupled axle instead of a second carrying axle. As a result it developed a higher tractive effort. It also had a Stephenson Long Boiler
, forked frame
and an outside Stephenson valve gear
with outside cylinders. The coupling rods were based on an American prototype. Later many of the engines were fitted with a Crampton boiler.
They were coupled to 3 T 4.2, and later 3 T 5, tenders

Long Boiler locomotive
The Long Boiler locomotive was the object of a patent by Robert Stephenson and the name became synonymous with the pattern.-History:It is generally perceived that it arose out of attempts to match the power of broad gauge locomotives within the limitations of the loading gauge of Stephenson railways...

Locomotive frame
A locomotive frame is the structure that forms the backbone of the railway locomotive, giving it strength and supporting the superstructure elements such as a cab, boiler or bodywork. The vast majority of locomotives have had a frame structure of some kind...

Stephenson valve gear
The Stephenson valve gear or Stephenson link or shifting link is a simple design of valve gear that was widely used throughout the world for all kinds of steam engine. It is named after Robert Stephenson but was actually invented by his employees....

Tender locomotive
A tender or coal-car is a special rail vehicle hauled by a steam locomotive containing the locomotive's fuel and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so tenders are necessary to keep the locomotive running over long distances. A locomotive...
