Rail Joints MCQ Questions - Railway Engineering

Explanation: Joint made up of 2 bars.

Explanation: True, The purpose of the rail joint are to hold the two ends of the rail in place and act as a bridge between rail ends

Explanation: Standard joint bars connect two rails of the same weight and section. They are typically 24 inch with 4 bolts ( for small rail section) or 36 inches with 6 bolts (for large rail section).

Explanation: The weakest link in a track is rail joint. There is a break in continuity of the rail at the joint because of presence of expansion gap and improper levels of rail heads.

Explanation: Three types of railways joints : Standard, Compromise, Insulated

Explanation: Non directional are used where the difference between sections is in the heights of the head.

Explanation: Joint is made up of two bars or more commonly called angled bars.

Explanation: Rail joints can be classified based on position of sleepers or position of joints. According to position of sleepers, the joints are Supported joints, Suspended joints and Bridge joints. Square joint is joint classified based on position of joints.

Explanation: Because of presence of joints, there are effects like noise pollution, sabotaging chances and excessive wear of track components. The train requires extra efforts to haul itself over these joints which leads to increase in fuel consumption.

Explanation: A high voltage source is used for energising a metal electrode which is then brought near another metal object. Heat is generated causing the two ends to weld. This type of welding can be done by using Insert plate technique, Scheron process or enclosed space technique.
