Rail-track protection

A signal box is an infrastructure allowing control of the various railway switches and protection signals with the purpose of management of railway fraffic within a geographically delimited rail track. 

In front of the building a timber floor protected by a eave should be laid. Trucks coming and going with materials should be moved by hand. Trucks with pneumatic-tyred wheels or barrows with bronze wheels are best for this purpose. If a narrow-gauged track is to be used, in the vicinity of buildings holding blackpowder, the rails should be of wood and the trucks should be fitted with bronze wheels. 

Control System (ETCS). ETCS is the Automatic Train Protection (ATP) system, and GSMR is the radio system for voice and data communication. Together, they form The European Rail Traffic Management System (ERTMS). The Radio Block Center (RBC) sends movement authority and track profiles to the train via GSM-R. The RBC is the link between the interlocking system, the train traffic control, and the train itself. The train reports its position to the RBC. Balises are read by the on-board antenna, processed by the ETCS onboard (trainbome) equipment and are used as position references for the train, i.e. they determine where the train is. 

Also, corrosion on galvanized steel poles and fences in the coastal area of Simonstown and Muizenberg (Indian Ocean, Cape Province) is pronounced. At a distance of 10-20 m from the ocean spray, severe corrosion occurs after 3-5 years. Only duplex systems offer sufficiently long protection against rust. Unprotected steel is perforated within only a few years, but this knowledge led to successful trials of galvanized rails for the railway track. 

In stray current forced drainage against rails, current peaks up to 100 A can occur, particularly in the protection of old pipe networks with poor coating, although the necessary output voltage remains quite low. This current depends on the voltage between rail and pipe as well as on the resistance of the circuit. With rails laid in the street and thus earthbound tracks, this is mostly between 5 and 10 V. The dc supply for such installations is therefore considerably less than for normal impressed current anode stations. 

Arnitel is used in large quantities for the protection of electrical cables and signaling cables for railways, mainly in areas exposed to high temperatures. It can also be found in railway pads , i.e., rubber mats that enable the use of railway tracks for longer periods without maintenance, and for damping the vibrations in the rail network. DSM offers a broad portfolio for this market there are different types for use in passenger lines (for instance, the TGV...
