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 Vehicle propulsion, drive, in which each floating axle has an individual motor, that is placed in the spring mounted locomotive frame. The weight of the driving Electric motor, 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, gear ... [...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 ('' Länderbahnen''). ...

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 (E 16 01 to E 16 10) was delivered in 1926, the second (E 16 11 to E 16 17) in 1927. The third, re-worked series (E 16 18 to E 16 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SBB Ae 8/14
The SBB 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 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. 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 the numbers 11801 a ...

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. Because of this drive construction, invented by Jakob Buchli, it was one of the longest-lasting Swiss locomotives. It was in regular use for 70 years, 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 Ae 3/6I, two prototypes of the Ae 4/7 were ordered in 1925. Subsequently, in total 127 were built between 1927 and 1935. 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 Ae 3/6 Series
The SBB Ae 3/6 is a series of electrical locomotives designed for both freight and passenger service on Swiss lowland railways. The series comprises three separate models: the Ae 3/6I, the Ae 3/6II, and the Ae 3/6III. They were constructed in lots between 1920 and 1929. They were the most numerous series of SBB locomotives constructed, and operated for around 70 years until the last units retired in 1994. The individual members of the series differ in how they are driven: the Ae 3/6I and Ae 3/6III by motors on each powered axle, and the Ae 3/6II by two motors connected to the center drive axle with countershafts, and then with rods to the other two driven axles. The asymmetrical undriven axle arrangement is due to the main transformer needing to be displaced to the front of the locomotive from the center of the body by the large traction motors located there. Background With the rapid electrification of the Swiss rail network in the early 20th century, the SBB urgently nee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
