Points and crossings

Lecture notes of Transportation engineering 2 point and points and crossings are provided facilitates the change of railway vehicles from one track to another. Points and crossings are arrangements that allow trains to move between tracks. They consist of movable rails called switches or tongues that can divert trains left or right. Crossings provide gaps in the rails so trains can move between intersecting tracks. Together, switches and crossings form turnouts that allow trains to change routes. Proper placement and angles of switches and Learn the Requirements of an Ideal Permanent Way in Railway Engineering for Civil Engineering. Coning of Wheels, Types of Rail Sections

Ballast in railway is layer of broken stones, gravel, moorum or any other gritty material, packed below and around the sleepers. Types of ballast in railway The components of a railway track are rail sections, sleepers, ballast, fasteners and roadbeds. Railway rail manufacturer YONGYANG will This presentation discusses points and crossings in railway systems. It defines points as movable sections of track that allow trains to change paths, and

Types of Rail Switches and Their Functions

The document discusses rails used in railway tracks. It defines different types of rails including double headed, bull headed, and flat footed rails. Flat footed rails, also called Vignoles rails, are now most commonly used. Standard rail sections used in Indian railways, such as 52kg and 60kg, are presented. Requirements of an ideal rail and factors affecting rail wear and failure are

The document discusses various types of track junctions and layouts used in rail transport. It describes turnouts that allow tracks to branch off in similar or contrary directions to the main line. It also covers symmetrical splits, three-throw switches, double turnouts, crossovers, diamond crossings, scissors crossovers, gauntleted tracks, gathering lines, triangles, and double Learn about the permanent way in railway engineering along with its components like cross-section, rails, sleepers, ballast, fixtures, fastenings with their types. Different types of crossings are classified according to angle (acute, obtuse, right) and diversion (spring, crossover, scissors, diamond, gathering lines). Components of turnouts like switches, stock rails, V-crossing, lead rails, and locking systems are also detailed along with their functions.

Types of rails are mainly divided into three. Double headed rails, bull headed rails and flat footed rails. You will come to know all the important details of each of them with figures in the blog. The advantages of flat footed rails are also vividly described.

The rail section whose head dimensions are more than that of their foot are called bull headed rails. In this type of rail the head is made little thicker and stronger than the lower part by adding more metal to it. These rails also require chairs for holding them in position. Bull headed rails are especially used for making points and crossings. RAILWAY SIGNALLING SWITCH & CROSSING COMPONENTS SWITCHES & CROSSINGS Commonly known as S&C Defined as track Basics of Switches and Crossings Abstract Switches and crossings are the essential elements of railway lines, stations and yards, in that they allow a train to change directions or a vehicle to be transferred from one track to another. Their main characteristics and classifications are concisely described in this chapter.

Multiple choice questions on railway engineering topic Points and Crossings. Practice these MCQ questions and answers for preparation of various competitive and entrance exams. Question: 1. What are the functions of points and crossings in railway track layout ? 2. Draw a neat sketch of right-hand or left hand turnout and show its various component parts. 3. What is meant by a turnout ? Enumerate component parts of a turnout with their functions. (P.B. June 1996, Dec. 1998). 4. What is a switch ? What are the component parts of a switch ?

Understand the Function of Sleepers in Railway Engineering for Civil Engineering. Learn how they support rails, maintain gauge, and ensure track stability. Switch – A pair of tongue with stock rail with necessary connections and fittings. Points – A pair of tongue rail with their stock rails are termed as points. Crossing – A crossing is a device introduced at the junction where two rails cross to permit the wheel flange of railway vehicle to pass from one track to another track.

Inspection of Points and Crossings

This procedure sets out the requirements for the maintenance of points and crossings by controlling lipping, metal flow & pitting. This is required to prevent early replacement of turnout steel components. This Article Covers Various Types Of Ballast, Sizes, Design And Functions Of Ballast One By One. Ballast is a layer of broken stones, gravel, moorum, or any other granular material placed and packed below and around sleepers for distributing load from the sleepers to the formation. It provides drainage as well as longitudinal and lateral stability to the track.

Points and crossings are critical components of railway networks that allow trains to switch tracks and safely cross other tracks. Turnouts, which combine points and crossings, enable trains to divert from one track to another or access sidings. They consist of switches, stock rails, crossings, lead rails, check rails, and wing rails. Points can be facing or trailing and turnouts can be right

Learner drivers are often caught out on pedestrian crossings in the driving test and it is a common reason for failing due to the strict regulations of examiners. In this article we will go through the different types of pedestrian crossings that you might come across, and how to approach these correctly to help you secure the driving test pass. The video lecture contains brief description about – 1. What is points & crossings ? 2. Components of crossings. 3. Types of crossing which are – On the basis of shape of crossing square crossing Design This section outlines the requirements for design of points and crossing assemblies and their interface with railway infrastructure including rollingstock. For the design and manufacture of specific points and crossing components also refer to ETA-03-03 Technical Specification for Manufacture of Components for Points Crossing Structures.

Pre monsoon and post monsoon maintenance: The rails, bolts, fish plates, components of points, crossings, etc. are subjected to corrosion due to effect of moisture in the rainy season are necessitate the maintenance of railway track. Components of railway track are rail section, sleepers, ballast, rail fastenings and subgrade and embankments. I will walk you through each of them in detail. You will get to learn about the functions of rails, functions of sleepers, functions of ballast and about fastening of railway. The rail provide a hard, smooth and unchanging surface for the passage of heavy

This document discusses various aspects of railway track components and infrastructure. It describes points and crossings which allow trains to divert from one track to another. It then discusses turnouts, their components like stock rails, crossings, and operating mechanisms. The document covers different types of stations like wayside, junction and terminal stations. It also 4. What are the different types of Points and Crossings used in railway systems? Ans. The different types of Points and Crossings include simple turnouts, double slip switches, diamond crossings, and scissors crossovers, each serving a specific purpose in enabling trains to change tracks or cross over safely. 5.

Components of railway track are rail section, sleepers, ballast, rail fastenings and subgrade and embankments. I will walk you through each of Railway turnouts can be divided into many types depending on the design, single turnout, curved turnout, equal slip, symmetrical turnout, diamond crossing and so on.
