Baden I b (old)
Encyclopedia
The engines of Baden Class I b were very early German steam locomotive
s built for the Grand Duchy of Baden State Railways.
in 1841 was the first locomotive to be built in Baden and the first of nine engines of its class. Kessler built this engine together with his partner Martiensen at his own expense and then placed it experimentally in service. Because it achieved the same level of performance as its English prototypes, it was taken over by the state railway.
On the line between Heidelberg
und Wiesloch
one locomotive achieved a speed of 54 km/h with 20 wagons. On a fast run the engines could manage 85 km/h.
The majority of the engines were retired by 1863. Only the last one was converted in 1854 into a tender locomotive
and stayed in service until 1867. She had a water capacity of 1.45 m³ and coal capacity of 1.8 t.
(Gabelsteuerung). The locomotive OFFENBURG had a Capry valve gear on delivery. The engines had improved running gear
however due to their adjustable leaf springs and centre axle box.
The last engine of this class, EXPANSION No. 15, had a Meyer double rocker (Doppelschwing) valve gear, a larger cylinder bore of 381 mm, higher boiler pressure of 5.0 bar and 101 heating tubes. Its larger heating area generated an increase in power.
The locomotives were originally built for 1,600 mm broad gauge
, but converted in 1854 to standard gauge
. At the same time they were given Capry valve gear, apart from CARLSRUHE and PHOENIX which were fitted with Stephenson valve gear
.
The engines had a Sharp boiler barrel. The vertical boiler had a rounded top. On the foremost boiler section was the steam dome
with a safety valve and spring balances. The frame
comprised two outside stiffener frame sections (Futterrahmen) and four plate frame sections (Plattenrahmen) for the steam engine. The EXPANSION had two plate frame sections.
The vehicles were equipped with a Kessler type tender of class 2 T 5.4 or 3 T 5.4.
Steam locomotive
A steam locomotive is a railway locomotive that produces its power through a steam engine. These locomotives are fueled by burning some combustible material, usually coal, wood or oil, to produce steam in a boiler, which drives the steam engine...

-Early history:Between 600,000 and 200,000 years ago, "Heidelberg Man" died at nearby Mauer. His jaw bone was discovered in 1907; with scientific dating, his remains were determined to be the earliest evidence of human life in Europe. In the 5th century BC, a Celtic fortress of refuge and place of...

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...
