Different Types Of Rail Joint

Rail Joint Definition

Encyclopedia has defined the word “rail joint” as the following: A splice connecting the adjacent ends of rails, in distinction from a chair, which is merely a seat. The two devices are sometimes united. Among several hundred varieties, the fish joint is standard. See Fish joint, under Fish.
Rail joint plays a jointing function (connecting function) in the railroad. High quality railway joint can effectively reduce the influence of wheels when passing through the jointing sections of the steel rail and increase the steadiness and continuity of the passing trains. As one of the important parts in railway, railway joint bar are widely used both in light rail and heavy rail to guarantee the safety of railroad transportation.
Rail joint for light rail: 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg and 30kg
Rail joint for heavy rail: 38kg, 43kg, 50kg and 60kg
Rail joint for crane rail: QU70, QU80, QU100 and QU120

 Different Types of Railway Joint 
Railway joint can be classified into many types, including common rail joint, compromise rail joint, bulge rail joint, insulated rail joint and glued insulated rail joint. Different types can be applied into different use.

 Common Rail Joint
Common rail joint is the most commonly used rail joint in the connecting of the steel rail, and it is usually with regular shape. There are two types, 4 holes And 6 holes. We can produce both types to suiting for your steel rails. In addition, we can also produce matching rail fish plate for different standard steel rail.

 Compromise Joint Bar
Compromise joint bar is usually to connecting two kinds of different rails, it can joint them together and fit each other exactly. Compromise joint bar can make the joint section flat and smooth. Because of the specific function of compromise joint bar, it has two different bars: gauge side joint bar and outside joint bar.

 Joggled Rail Joint
Joggled rail joint, also named bulge rail joint, it has a prominent bulge section in the middle. Different from other rail joint, rail bulge rail joint is generally used in broken welded rails or temporary repair of cracked welded rail joint with an emergency clamp. It can be used in various rail sections and it is useful as the temporary repairing.

 Insulated Rail Joint
Insulated rail joint is electrical resistance, and it is usually used in electrical section of railway track. It is usually consist of insulated materials on the surface of railway joint, which can prevent the signal and electric transmission. There are two types of end post of Insulated rail: glued end post, inserted end post.

 Glued Insulated Rail Joint
Glued insulated rail joint is generally used in long welded rails. With minimum number of installing components, it is easy to install glued insulated rail joint. It is the right place in track-circuited area to install glued insulated rail joint.

Factors affecting the alignment of hill road

-
Image
The main factors to be considered while deciding the alignment of hill roads, are as discussed. Length : The cost of construction of a hill road per kilometer length is comparatively very high. It should therefore be ensured that length of the road connecting two stations should be minimum possible, adopting ruling gradients along its most of the length. Altitude of the road : At lower altitudes, large number of cross drainage works are required to be constructed. Where as at higher altitudes, the road pavement may witness snowfall during winter. This is why the align-ment of hill roads should preferably by provided at an altitude between 900 m slopes exposed to sum. The hill slopes which are subjected to high winds should never be selected unless and until there is no other alternative. In northern hemisphere, southern slopes of the hills are more suitable than northern slopes which remain tin shades and are usually subjected to high winds. Saddles or Passes : While locating ...

Sleepers The members which are laid transverse to the rails on which the rails are Supported and fixed to transfer the loads from rails to the ballast and sub grade below. Functions 1)       To hold the rails to correct gauge. 2)       To hold the rails in proper level. 3)       To act an elastic medium in between ballast and rails. 4)       To distribute the load from rails to index area of ballast underlying it. 5)       To support the rails at a proper level in straight tracks and proper super elevation on curves. 6)       It also gives lateral and longitudinal stability of the permanent track. 7)       To rectify the track geometry during service life. Requirement        i.           They should be economical i.e...
