The vehicles of type Ia were the first locomotives of the Grand Ducal Baden State Railway . To distinguish it from the locomotives named after the new scheme introduced in 1868, this class is also referred to as Ia (old) .
The vehicles built in England (like most locomotives in the early days of the railway) were used on the route between Mannheim and Heidelberg . This was set up by the Grand Duchy of Baden on March 29, 1838 (see also Badische Hauptbahn ). The line, which went into operation on September 12, 1840, was built in 1,600 mm wide gauge .
A total of six machines were manufactured by Sharp, Roberts & Co., two each in 1839, 1841 and 1843. They were given track numbers 1 to 6 and the names LOEWE , GREIF , HEIDELBERG , MANNHEIM , ROBERTS and FREIBURG . From 1841 Emil Keßler built nine more copies, which were designated as type I b .
Like the Adler , the vehicles had a 1A1 ("Patentee") wheel arrangement, but were significantly larger and more than twice as heavy. They had an inner panel frame and an additional outer frame. The cylinders were located under the smoke chamber between the inner and outer frames. The standing tank was arranged between the driving axle and the rear running axle. Originally the locomotives had an internal fork control, but this did not prove itself and was later replaced by a Capry control. The locomotives did not have a driver's cab, and wind protection was not yet common at that time.
The first two locomotives had a cylinder diameter of 305 mm, the two following 330 mm and the last two 356 mm. The first two locomotives were later converted to 330 mm.
The vehicles were equipped with type 2 T 4.05 - 2 T 4.32 tenders . In 1854/55 the locomotives were converted to standard gauge . The locomotives 3, 5 and 6 were converted into tank locomotives and provided with a windbreak. In 1865 they were retired. Due to the narrower track, the fire box had to be made smaller, which led to a reduction in performance.
Parts of the other locomotives were used in the construction of their successors ( Ic , later IIa old) in 1856 . The wheels of the running axles, some fittings, the nameplates and the tenders were taken over.
