The steam locomotives of the A 4 series were acquired by the Reichseisenbahnen in Alsace-Lorraine in 1871. The express locomotives had the 1B wheel arrangement.
history
With the takeover of the route network in Alsace-Lorraine, the acquisition of locomotives and wagons was necessary because the French had withdrawn all vehicles. The Reichseisenbahnen therefore acquired four passenger locomotives from the English Somerset and Dorset Railway . The machines were manufactured by the Vulcan Foundry in 1866 . The locomotives were given the numbers 21 to 24 at the SDR and later the numbers 26 to 29 at the Reichseisenbahnen as well as names of rivers. In 1898, numbers 26 and 29 were still given counterweights on the coupled wheels. The first locomotive was taken out of service in 1882, the last followed around 1900.
Constructive features
The locomotives had an outer frame. The kettle was three-section and had a very high standing kettle.
Like the control, the two-cylinder wet steam engine was internal. The suspension of the coupling axles was provided by leaf spring packages below the axle. The barrel axle was cushioned by overhead leaf spring packages.
There was a sandpit on either side of the perimeter that sanded the first coupling axle.
The locomotives were coupled to a three-axle tender with a 9 m³ water tank volume.
