The E were steam locomotives of the Royal Württemberg State Railways , built by the Belgian company Cockerill from Seraing . The three-cylinder compound locomotives with the 1'B1 'wheel arrangement were procured for express train service .
history
Until the beginning of the 1890s, class A locomotives could handle express train traffic without any problems. From this time on, however, there was a need for more powerful machines due to the increase in train mass and speed. Since Maschinenfabrik Esslingen was busy developing the heavy class G freight locomotive , the order went to the Belgian manufacturer Cockerill.
In 1892 10 locomotives were built, which were given the road numbers 401 to 410.
They were similar to the 12 series from Belgium. Cockerill was only given the basic design concept. Compared to the Belgian type, they had a larger kettle. The machines were designed for a boiler overpressure of 15 kp / cm², but operated at 12 kp / cm². Of the three cylinders, the high pressure cylinder was located between the other two. The grate had a stepped firebox supported . The locomotives could be operated as triples or compound machines and had a reset device for the running wheel sets controlled by the tender clutch .
According to Hermann Lohr and Georg Thielmann, an overload of the trailing axle can be seen externally. The front overhang due to the arrangement of the cylinders in front of the barrel axis was noticeable at higher speeds. The planned top speed of 80 km / h was later reduced to 75 km / h. The machines carried 150 t at 60 km / h on a 10 ‰ gradient.
Until 1903 they were used in the heavy express train service between Bretten and Ulm . They reliably provided the high-quality express train service including the transit traffic of international express trains. After that they were stationed in Heilbronn . In 1921 the locomotives were retired
Constructive features
The locomotive boiler was designed as a Belpaire boiler , the long boiler had three boiler sections and a large steam dome on the front boiler section. The pipe length was 4.295 m, the grate area 2.0 m² and the heating area 148.0 m², the operating pressure was 12 kp / cm². The 250 heating tubes had a diameter of 45 mm. The center of the boiler was 2150 mm above the top of the rail.
The sheet metal frame was designed on the inside . The frame sheets were 30 mm thick.
The locomotives had a wet steam - three-cylinder compound engine with two horizontally arranged outer cylinders and an inner cylinder and could be operated in a simple steam expansion as well as in composite action. When operated in combination, the inner cylinder worked as a high pressure cylinder and the outer cylinder as a low pressure cylinder. A changeover valve could be used to switch to simple steam expansion when starting up, and an auxiliary steam control was used to switch to composite action. The crosshead guidance was two-rail, the first coupled axle was driven . The Allan control was arranged separately and adjustable.
The drive wheels had a diameter of 1650 mm, the leaf springs were arranged under the axle bearings and connected by compensating levers. The running wheels were 1045 mm in size, the running axles were connected to the tender coupling by a Klose steering mechanism and were radially adjustable. The front running axle spring was arranged above, the leaf spring of the trailing axle was moved backwards with an intermediate lever. The distance between the leading axle and the first coupling axle was 1,832 mm, between the two coupling axles it was 2,135 mm and between the second coupling axle and the trailing axle again 1,832 mm.
The knee lever brake acted on the coupling wheels on one side from the inside. The sandpit on the sheet metal in front of the first coupling axle sanded the first coupling axle on one side from the front. The locomotives had wheel arches cut out above the coupling wheels. The locomotives were coupled with type 2 T 10 tenders .
