Speno
Speno International SA is a manufacturer of railway track maintenance machines. The Speno company was founded by Frank Speno in 1960 and is now headquartered in Switzerland. It operates maintenance trains in many countries. The ''Speno'' trains are bright yellow in color. Main activities The activities of Speno are: :* grinding and re-profiling of tracks and points :* measuring rail surface faults and profiles :* checking for internal rail flaws with ultrasound. Grinding For railgrinding, Speno has developed a range of specialized trains and machines to support these activities. There are standard grinders for open tracks (normal train tracks), tramways, subways, regional railways (mixed train, tram, metro) and specialized areas like bridges, switches, etc. Measuring and inspection The other main activity for which specially designed Speno trains are used is measuring and inspecting railway tracks. With these trains the tracks can be inspected in "real time" while the train run ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stavoren
Stavoren (; fry, Starum; previously Staveren) is a city in the province of Friesland, Netherlands, on the coast of the IJsselmeer, about 5 km (3.1 mi) south of Hindeloopen, in the municipality of Súdwest-Fryslân. Stavoren had a population of 950 in January 2017. It is one of the stops on the Elfstedentocht (English: "eleven cities tour"), an ice skating contest that occurs when the winter temperatures provide safe conditions. A ferry for pedestrians and cyclists operates between Stavoren and Enkhuizen, with increased trips during summer months. The Friese Kustpad, a 131 kilometres (81 miles) long-distance trail to Lauwersoog, begins in Stavoren. History The historical Stavoren was granted city rights between 1060 and 1067, making it the oldest city in Friesland. It is mentioned in early texts as the burial place of the early kings of Friesland, including the first Christian king Adgil II (d. 730), who was a son of Redbad, the last pagan king who lived from about 670 ...

Maintenance Of Way
Maintenance of way (commonly abbreviated to MOW) refers to the maintenance, construction, and improvement of rail infrastructure, including Railway track, tracks, ballast, grade, and lineside infrastructure such as Railway signal, signals and signs. Track The most fundamental maintenance of way task is the construction, repair, and replacement of the track and its supporting ballast and grade. The task was once done entirely by manual labor, but in the 21st century, track maintenance is largely done by specialized machines that are much faster and require fewer people to accomplish the same amount of work. Electrification systems On rail lines, which include electrification by a third rail or an overhead line, maintenance of way work includes repairing and replacing the systems.

Automatische Treinbeïnvloeding
Automatische TreinBeïnvloeding or ATB (English: Automatic Train Control) is a Dutch train protection system first developed in the 1950s. Its installation was spurred by the Harmelen train disaster of 1962. ATB operates by the train collecting electrical signals from line-side apparatus and will override the driver's controls in the following situations: * a) failure to reduce speed at a caution signal (ATB will slow the train sufficiently to stop at the next signal). * b) failure to observe speed limit (ATB makes an immediate emergency brake application) ATB-EG ATB-EG ''(''ATB Eerste Generatie ''English: ATB First Generation'') is based on the American Pulse Code Cab Signaling system. It is installed on all major Dutch rail lines Technical overview ATB-EG controls 5 speeds: 40 km/h, 60 km/h, 80 km/h, 130 km/h and 140 km/h. Just like Pulse Code Cab Signaling the system works by sending pulses along the AC track circuit. When the circuit is closed by ...

Buffer Stop
A buffer stop, bumper, bumping post, bumper block or stopblock (US), is a device to prevent railway vehicles from going past the end of a physical section of track. The design of the buffer stop is dependent, in part, on the kind of couplings that the railway uses, since the coupling gear is the first part of the vehicle that the buffer stop touches. The term "buffer stop" is of British origin, since railways in Great Britain principally use buffer-and-screw couplings between vehicles. Types Several different types of buffer stop have been developed. They differ depending on the type of coupler used and on the intended application. * Buffer stops with anticlimbers. These are particularly important for passenger railway applications, because the anticlimbers reduce the likelihood of telescoping of the railroad cars during a head-on impact. * Buffer stops for a knuckle coupler or an SA3 coupler (centrally positioned between the two rails) * Buffer stops with traditional " ...

Railgrinder
A railgrinder (or rail grinder) is a maintenance of way vehicle or train used to restore the profile and remove irregularities from worn tracks to extend its life and to improve the ride of trains using the track. Rail grinders were developed to increase the lifespan of the tracks being serviced for rail corrugation. Rail grinding is a process that is done to stop the deformation due to use and friction on railroad tracks by removing deformations and corrosion.Corrugation."Corrugation-Research and Facts". Retrieved on 2017-03-27. http://www.corrugation.eu/index.asp. Railroad tracks that experience continual use are more likely to experience corrugation and overall wear. Rail grinders are used to grind the tracks when rail corrugation is present, or before corrugation begins to form on the tracks. Major freight train tracks use rail grinders for track maintenance based on the interval of tonnage, rather than time.Magel, E., Roney, M., Kalousek, J. and Sroba, P. "The Blending of T ...
