Wiesen Viaduct
The Wiesen Viaduct (or Wiesener Viaduct; german: Wiesener Viadukt) is a single-track railway viaduct, made from concrete blocks with dimension stone coverage. It spans the Landwasser southwest of the hamlet of Wiesen, in the canton of Grisons, Switzerland. Designed by the then chief engineer of the Rhaetian Railway, Henning Friedrich, it was built between 1906 and 1909 by the contractor G. Marasi (Westermann & Cie, Zürich) under the supervision of P. Salaz and Hans Studer (RhB). The Rhaetian Railway still owns and uses it today for regular service. An important element of the Davos–Filisur railway, the viaduct is high and long; it has a main span of . Location The Wiesen Viaduct forms part of the Davos–Filisur railway section between Wiesen and Filisur. Just southwest of Wiesen railway station, it has, on its south side, a separate pedestrian bridge giving hikers access to Filisur. At the western end of the viaduct is a non functioning Hippsche turning wheel. History ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Push–pull Train
Push–pull is a configuration for locomotive-hauled trains, allowing them to be driven from either end of the train, whether having a locomotive at each end or not. A push–pull train has a locomotive at one end of the train, connected via some form of remote control, such as multiple-unit train control, to a vehicle equipped with a control cab at the other end of the train. This second vehicle may be another locomotive, or an unpowered control car. In the UK and some other parts of Europe, the control car is referred to as a ''driving trailer'' (or driving van trailer/DVT where there is no passenger accommodation); in the US and Canada, they are called ''cab cars''. Train formation Locomotive at one end Historically, push–pull trains with steam power provided the driver with basic controls at the cab end along with a bell or other signalling code system to communicate with the fireman located in the engine itself in order to pass commands to adjust controls not ...

Hipp Reversible Disk Signal
The ''hippsche Wendescheibe'' or '' Hipp’sche Wendescheibe '', is a historical railway signal. The automatic and visual signal served as distant signals and home signals. Its main advantage was that energy to move the signal was provided locally, while the low power impulse to move the signal was transmitted electrically from the signal box, thus minimizing cumbersome and unreliable energy transmission over distance. Description History This type of signal was developed by the inventor and watchmaker Matthäus Hipp and first used in Winterthur in 1862. The signal is named after him and was in use long before the wing signals. How it works The Hipp reversible disc signal is mounted on a hollow cast column. This carries a sheet metal disc about 1m in diameter. Until 1877 the disc was painted red on both sides with a white border, but later on one face red with a white diagonal bar and on the reverse white and black, partly chequered, partly with a diagonal bar, or simply paint ...
