Rails used on the railway

What tracks? Rails used on the railway. Direct rail / guide trains without the need for control. Rail tracks are the two rigid rods the same length as the bearing mounted on the base runway. Rails are tied to the rail pads using a nail, screw fastening, or fastening e (such as fastening Pandrol). Kind of type used depends on the type of bearing used. Puku fastening screws or nails used in wooden bearings, while e is used for fastening bearing concrete or cement.

Rail is usually installed on top of a stone path lined with kericak otherwise known as a ballast. Ballast works on the railway to reduce vibration and diffraction due to heavy rail trains. To cross the bridge, used timber bearing a more elastic than concrete pads.
Rails are made of what?
Trunk rail made of iron or steel high pressure, and also contains carbon, manganese, and silicon. Trunk rails specially made to withstand heavy loads (axle load) of a series of trains that run on it. This is the first component that receives a transfer weight (axle load) of a series of passing trains. Each piece (segment) stems 20-25 m long rails have for modern rail, while for rail jadul only 5-15 m length of each segment. Trunk rail is divided into several types based on the weight bars per meter length. Indonesia has four types of stem tracks, namely R25, R33, R42, and R54. Suppose, R25 means the trunk rail weighs an average of 25 kilograms / meter. The greater the "R", the stem loop was too thick. Differences in rod-type rail affects several things, among others (1) a large maximum pressure (axle loads) that could be accepted when the train crossed the tracks, and (2) the allowable speed train speed as it passes through the rail. The greater the "R", then the greater the axle load which could be accepted by the rail, and trains that pass on it can be traveling at high speed with a stable and secure
