1. IRON STEEL BAR
rail rod made of iron or steel high pressure, and it also contains carbon, manganese, and silicon. Rail rod specially made so that it can withstand heavy loads (axle load) of the series of trains that run on it. This is the first time the component is receiving the transfer weight (axle load) of a series of trains passing by. Each piece (segment) rail rod has a length of 20-25 m for modern rail, while for the old school tracks only 5-15 m length of each segment. Trunk rail can be divided into several types based on weight bars per meter length.
In Indonesia, the four kinds of rail rod, ie R25, R33, R42, and R54. For example, R25 means rail rod has an average weight of 25 kilograms / meter. The greater the "R", the thicker the stem also this list tersebut.Berikut rail used rails in Indonesia using standard UIC with Standards:
• Rel 25 which means each 1 meter piece of rail weight is 25 kilograms (kg).
• The rails 33 which means each 1 meter piece of rail weight is 33 kilograms (kg).
• The rails 41 which means each 1 meter piece rail weight is 41 kilograms (kg).
• The rails 42 which means each 1 meter piece rail weight is 42 kilograms (kg).
• Rel 50 which means each 1 meter piece rail weight is 50 kilograms (kg).
• The rails 54 which means each 1 meter piece rail weight is 54 kilograms (kg).
• The rails 60 which means each 1 meter piece rail weight is 60 kilograms ( kg).
The difference in the type of trunk rail affects several things, among others, (1) large maximum pressure (axle load) which could be accepted when the railway tracks passing, and (2) the allowable rate of speed railway as it passes through the rail. The greater the "R", the greater axle loads that could be accepted by the rail, and trains passing over it can run at high speed with a stable and safe.
Type the greatest tracks used in Indonesia is the UIC R54) used for railway line of heaviest traffic, such as cross-Trans Jakarta and Java. Not to forget the coal transportation cross-Lampung in South Sumatra that has highest axle load in Indonesia.
