Buchli Drive
The Buchli drive is a transmission system used in electric locomotives. It was named after its inventor, Swiss engineer Jakob Buchli. The drive is a fully spring-loaded drive, in which each floating axle has an individual motor, that is placed in the spring mounted locomotive frame. The weight of the driving motors is completely disconnected from the driving wheels, which are exposed to movement of the rails. First used in electric locomotives from the 1920s, the Buchli drive made possible the construction of faster and more powerful locomotives that required larger and heavier traction motors. The system minimises the impact on rail tracks due to the reduction in the overall unsprung weight. Although the drive was very successful though the 1930s, it is little used in modern locomotives, having been replaced with smaller, simpler drives that exhibit less imbalance and allow higher speeds. Construction In a Buchli drive a driven gear wheel is securely fixed to the locomotive f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deutsche Reichsbahn-Gesellschaft
The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The ''Deutsche Reichsbahn'' has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932"; nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history". Overview The company was founded on 1 April 1920 as the ("German Imperial Railways") when the Weimar Republic, which still used the nation-state term of the previous monarchy, (German Reich, hence the usage of the in the name of the railway; the monarchical term was ), took national control of the German railways, which had previously been run by the German states. In 1924 it was reorganised ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DRG Class E 16
The DRG Class E 16 were German electric locomotives in service with the Bavarian Group Administration of the Deutsche Reichsbahn, and were conceived as motive power for express trains. They were initially designated as the Bavarian Class ES 1, before being incorporated into the DRG numbering plan as E 16. History The first series (E16 01-10) was delivered in 1926, the second (E16 11-17) in 1927. The third, re-worked series (E16 18-21) was transferred to the Deutsche Reichsbahn in 1932 and 1933. Numbers E 16 11 and E 16 13 were lost in the Second World War, E 16 12 was retired in 1967 after an accident. With the introduction of the DB classification system on 1 January 1968, the remaining 18 Class E 16 engines were regrouped into Class 116. Between 1973 and 1980 the engines were gradually withdrawn from service. On 31 January 1980, the last Class 116 locomotive, number 116 009, was finally retired.

SBB Ae 8/14
The SBB-CFF-FFS Ae 8/14 is a class of electric locomotives built for Swiss Federal Railways to be used on the Gotthard railway. Only three prototype engines were built between 1931 and 1938, each of them in a different design. The steep 2.7% grades of the Gotthard Railway are challenging for the railroad operation. In the 1920s the trains became so heavy that the power and the traction of one locomotive became insufficient and so costly double-heading or splitting of the train over the mountain was required. The Multiple-unit train control was at that time emerging and not yet a reliable working system. The idea was to introduce double-locomotives with eight axles and a weight of 250 tons. These locomotives could pull the trains directly from Zurich or Lucern over the Gotthard and Monte Ceneri to Chiasso. This eliminated the stops for adding and removing additional locomotives in Erstfeld or Biasca, so that shorter travel times would be possible. First two prototypes with ...

SBB-CFF-FFS Ae 4/7
The Ae 4/7 was a universal locomotive of the Swiss Federal Railways, employing the so-called Buchli drive. Thanks to this drive construction, invented by Jakob Buchli, it was one of the longest-lasting locomotives. It was in regular use for 7 decades, from the 1920s into the 1990s, hauling freight and passenger trains all over Switzerland. History In the 1920s stronger locomotives were needed for the Swiss plateau (which has grades up to 12‰). The existing locomotives with three driven axles were a bit weak for their services. Because the Buchli drive already proved to be reliable on the , two prototypes of the Ae 4/7 were ordered in 1925. Subsequently, in total 127 were built between 1927 and 1934. While the mechanical part was built by the Swiss Locomotive and Machine Works, the electrical equipment was built in three varieties, because these parts were built by three different manufacturers, Brown, Boveri & Cie.

SBB-CFF-FFS Ae 4/8
The Ae 4/8 was a prototype locomotive of the Schweizerischen Bundesbahnen (Swiss Federal Railways) (SBB) for the testing of electrical operation. The locomotive was equipped with two different drives, therefore acquiring the nickname ''Bastard''. Because of its three-part locomotive body it also acquired the nickname '' Tatzelwurm''. History During the First World War the SBB decided to establish electric operation on their main lines as fast as possible, in order to become independent of coal supplies which had to be obtained from their warring neighbouring countries. Since electric traction technology was still new, suitable locomotive configurations had to be found. Therefore, the SBB ordered several prototype locomotives. In addition to the Be 3/5 12201, Be 4/6 12301, Be 4/6 12302 and Ce 6/8I 14201 with coupling rods, the SBB procured the Be 2/5 prototype locomotive with fully spring-loaded drives. When tested in the operational environment, this locomotive turned out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
