Functions of Good Rail Joint

Rail Joints are used to fasten steel rail together with fish bolts and nuts. rail ends between fishplates are held in same horizontal and vertical positions. A ideal rail joint should be able to perform the following functions:

• It should hold the rail ends in the correct position, horizoontal and vertical level.

• It should provide elasticity equal to steel rail

• It should allow certain degrees of free expansion and contraction of the rail.

• As the contact surfaces wear out under traffic, necessary adjustment in the joint should be possible to retain level and line.

• The joint components: fish bolts and nuts, fish plates should not be too heavy.

• It should be easy to maintain and the cost of maintenance should be minimal. Rail jont cost is nearly 1/4 percent of track maintenance cost.

It should permit easy replacement of any single rail from track.
