The wheels of trains are shaped conically, sloping at an angle of 1 in 20 to match the conical slope of the rails. This coning prevents lateral movement between the wheels and rails that could cause uneven load distribution. On straight tracks, coning ensures the wheels roll along the center of the rails without touching the flanges. On curved tracks, the increased diameter on the outer wheels and decreased diameter on inner wheels compensates for the greater distance the outer wheels must travel due to centrifugal force. Coning reduces lateral movement and contact between flanges and rails to allow for smooth train movement.

Coning of Wheels in Railways & Rail Creep
This document discusses coning of wheels and rail creep in railways. It contains the following key points:
1. Coning of wheels refers to wheels being shaped like a cone to keep trains centered on straight tracks and allow different wheel distances on curved tracks, reducing wear.
2. Rail creep is the longitudinal movement of rails in the direction of train movement, ranging from 0-6 inches. It is caused by starting/stopping forces, wave motions, and temperature changes.
3. Creep can cause buckling, disturbed track alignment and gauging, and disrupted signaling if not corrected through pulling rails back or using creep anchors to grip rails in place.
11.track junctions and layouts
Track junctions transfer rail vehicles between tracks or allow them to cross tracks. There are several types of simple track layouts for junctions depending on traffic needs. Common layouts include turnouts that continue or change the direction of travel, symmetrical splits that divert tracks in two directions with equal radii, and three-throw switches that allow movement in three directions but are now obsolete due to safety concerns. More advanced layouts include double turnouts, diamond crossings, scissors crossovers, triangles, and double junctions.
Rail fastenings and joints
The document discusses various track fittings and fastenings used to join rails and secure them to sleepers. It describes fish plates which join two rails together and allow for expansion and contraction. Fish plates are bolted to the rails using fish bolts. Spikes such as dog spikes and screw spikes are used to fasten rails to wooden sleepers. Chairs support bullheaded rails and are fixed to sleepers using spikes or bolts. Keys are also used to further secure rails in chairs. Bearing plates are placed under rails to distribute load across sleepers.
Creep of Rails.pdf
Creep is the gradual longitudinal movement of rails in the direction of dominant traffic over time. It is caused by various factors like wave action from moving loads, percussion from wheel impacts at joints, drag from locomotive wheels, and thermal expansion/contraction. Creep can be measured using creep indicators and causes issues like disturbed track geometry and signaling. Sections prone to high creep include grade transitions, structures, and points/crossings. Preventative methods include pulling rails back periodically, using anchors to fix rails to sleepers, and installing steel sleepers for increased stiffness.
Chapter 7 Maintenance of railway track
The document discusses the maintenance of railway tracks. Regular maintenance is needed due to factors that degrade tracks like heavy train loads, weather effects, and curvature stresses. Good maintenance provides benefits like increased safety, lower operating costs, and higher train speeds. Maintenance includes daily checks by track gangs and periodic inspections every 2-3 years to repair defects. Special pre- and post-monsoon maintenance is also required to address corrosion from monsoon rains.
Railway track construction, drainage & maintenence
The document discusses the construction and maintenance of railway tracks. It covers the need for constructing new railway lines, the process of construction including earth work, plate laying, and ballast laying. It also discusses track drainage systems, including surface drainage with side drains and sub-surface drainage. Maintenance of tracks is important and includes daily and periodic maintenance to replace components and ensure safety. Regular maintenance extends the life of tracks and rolling stock.
5.track or permanent way and track stresses
The document discusses the components and stresses acting on railroad tracks. It describes the main parts of a track including the rails, sleepers, ballast, and formation. The rails are joined by fish plates and bolts and fastened to sleepers. Sleepers are embedded in ballast which provides drainage and load distribution. A good track requires proper gauge, cross-leveling, alignment, gradient, and resilience to provide a comfortable ride while withstanding forces from train movement and varying temperatures. Wheels are coned rather than flat to reduce wear on flanges and rails and allow for lateral movement.

It then covers the history of railways in India from 1832 to present day. Key topics include gauges used in India, permanent way components like rails and fish plates, and manufacturing units.
railway failure and its type
This document discusses various topics related to railway tracks, including reasons for rail failures, types of rail failures, causes and measurement of creep in rails, methods to correct creep, types of rail joints, requirements of an ideal rail joint, types of rail fastenings, and requirements of sleepers. It provides details on factors that influence rail failure, different types of rail failures such as crushed head, transverse fissure, etc. It also discusses various causes of creep in rails and methods to measure and correct creep, including pulling back rails and using creep anchors.
Railway engg geometric design
This document discusses various aspects of railway track design including gradients, horizontal and vertical curves, super-elevation, and transition curves. It provides formulas for calculating ruling gradient, super-elevation, safe speeds on curves, and other key design elements. Track must be designed to suit the loads and speeds of trains based on safety and economic standards. Proper gradient, curvature, and super-elevation are necessary for smooth train operation.
Points and crossings
Turnouts allow trains to change tracks and directions by using a combination of points and crossings. Points consist of movable tongue rails and stationary stock rails, while crossings connect intersecting tracks using wing rails and a V-shaped nose. There are two main types of turnouts - left-hand and right-hand - depending on the direction trains divert. Proper turnout design and components like check rails are important for train safety given they are weak points on the track. Different types of crossings exist depending on the angle of track intersection, including acute, obtuse, and square crossings.
Sleepers and Ballast
Sleepers are transverse members that support the rails and transfer loads from the rails to the ballast and subgrade. The main types of sleepers discussed are timber, cast iron, steel, and concrete. Sleepers must meet requirements like being economical, easy to maintain, and able to withstand shocks and vibrations. Ballast is layered beneath and around sleepers to distribute loads, provide drainage and stability. Common ballast materials are broken stone, sand, slag, and moorum. Tractive resistances oppose train movement and include train resistance, track profile resistance, starting/acceleration resistance, and wind resistance.
Construction of a New Railway Track
The construction of a new railway track involves three main stages: earth work to prepare the formation, plate laying which involves laying rails and sleepers, and laying of ballast. There are different methods for plate laying such as the tramline method, telescopic method, and American method. Maintenance of the track is also important and involves daily inspection and maintenance as well as periodic maintenance to detect defects.
PERMANANT WAY
This document discusses various aspects of railway track design and maintenance. It covers topics like alignment surveys, track gauges, stresses in tracks, rail selection, wear testing, corrugation and creep of rails, rail joints, welding of rails, and types of rail sections. Permanent way requirements include uniform gauge, proper rail leveling, strength against lateral forces, well-designed curves and gradients, minimum tractive resistance, and facilities for drainage and repairs. Coning of wheels is described as well as different rail gauges used in India like broad, meter and narrow gauge. Rail functions and requirements for an ideal section are also outlined.
Points and crossing
Points and crossings are railroad track components that allow trains to be diverted from one track to another. A point, or switch, is a movable section of rail that can be aligned to direct trains to the left or right. A crossing is a section of overlapping rails that allows trains to pass through an intersection. Together, points and crossings make up a turnout, which consists of a stock rail, tongue rail, heel block, and other parts to smoothly guide trains between tracks in either a left-hand or right-hand configuration.
2.railway track gauge
The document discusses railway track gauges in India. It begins by defining gauge as the distance between rails and notes the three primary gauges used in India: broad gauge, meter gauge, and narrow gauge. Broad gauge is the standard at 1676 mm. Efforts are being made to convert other lines to broad gauge when funds allow due to its benefits. Factors like cost, traffic capacity, terrain, and ensuring uniformity across networks influence gauge choice. The document outlines problems caused by multiple gauges and India's policy to adopt broad gauge uniformly to eliminate issues and improve efficiency.
Left hand turnout
This document discusses railway turnouts. It begins by defining a turnout as the combination of points and crossings that allows a train to move from one track to another, either parallel or diverging. It then describes the key components of a turnout, including tongue rails, stock rails, lead rails, and a vee crossing. It also explains the classification of turnouts as left-hand or right-hand depending on the direction of diversion. Diagrams are included to illustrate the components and working principle of a turnout. The document concludes by stating that turnouts are essential for diverting traffic but can cause issues if not designed and maintained properly.
Railway engineering
Railway engineering involves the design, construction, and operation of railroads and mass transit systems. It is a branch of civil engineering that deals with track design, station layout, signaling systems, and train movement control. Typical tasks for railway engineers include determining horizontal and vertical alignment, estimating construction costs, and establishing signaling and control systems. Railway tracks consist of rails laid on sleepers embedded in ballast. Points and crossings allow trains to switch tracks. A variety of signals are used to safely direct train movement.
Site distance in highway engineering
The clear distance ahead of vehicle which is visible to the driver is known as sight distance
The minimum distance within which a driver can safely stop his vehicle without any collision with some vehicle, animal or any other object is known as stopping sight distance.
1.railway intro and rails
Railways use flat-footed rails made of high-carbon steel that are designed to carry heavy loads with minimal friction. Rails must withstand wear from loads as well as lateral and braking forces. They transmit loads to sleepers to reduce pressure on the ballast and formation below. Various types of rail sections have been used throughout history, with flat-footed rails now comprising 90% of tracks due to their stability and load distribution advantages. Rails experience wear at the top, ends, and sides that must be managed through alloy selection, maintenance practices, and design approaches like check rails and rail tilting.
Steering wheel alignment .
Wheel alignment refers to adjusting the angles of a vehicle's wheels to optimize handling and reduce tire wear. There are three main alignment angles: caster, camber, and toe. Caster involves tilting the steering pivot point forward or backward. Camber involves tilting the top of the wheel inward or outward. Toe involves angling the wheels slightly inward (toe-in) or outward (toe-out). Proper alignment settings improve tire wear, straight-line stability, and cornering ability. Alignment should be checked if a vehicle exhibits uneven tire tread wear, pulling, steering wheel issues, or vibrations.

Common bearing types are ball bearings and roller bearings. The document also discusses different types of friction including rolling friction, boundary friction, and their role in mechanical systems.
Unit 1 gauge creep
This document discusses gauge, coning, and tilting in railway tracks. It provides details on:
- The gauge is the distance between rails and is important for track alignment and stability. Wheels are coned to smoothly navigate curves and counteract centrifugal forces. Rails are tilted inward to reduce wear on outer rails and wheels.
- Coning wheels means making the outer wheel's tread circumference larger than the inner wheel's to maintain alignment through curves. Tilting rails inward at a 1 in 20 slope matches the wheel cone and distributes wheel loads evenly.
- Correct gauge, coning, tilting and cross-leveling are required for smooth riding, reduced component wear, and shock absorption
rear axles.pptx
The rear axle transmits power from the differential to the driving wheels. It consists of two half shafts connected by the differential. There are several types of rear axles, including semi-floating, full-floating, and three-quarter floating axles. Wheels are mounted on stub axles at the front and connected to the front axle via kingpins. Wheels can be pressed steel, wire, or light alloy.

It describes the purpose of the steering system to convert the rotary movement of the steering wheel into angular turns of the front wheels. It then explains different steering layouts such as swinging beam, fixed beam, and Ackermann steering principles. It also discusses steering angles including caster angle, camber angle, and kingpin inclination. Finally, it covers steering gears, power steering systems, steering linkages, and ball joints.
FARM TRACTORS UNIT 3
The steering system allows the driver to control the direction of the vehicle by turning the front wheels. It consists of several main components including the steering wheel, steering column, steering gear, pitman arm, drag link, tie rods, and spindles. When the driver turns the steering wheel, it rotates the steering shaft and gear which turns the pitman arm. The pitman arm then pushes or pulls on the drag link and tie rods to rotate the spindles and turn the front wheels. This allows the vehicle to change direction as the driver intends.
Unit 1 Front Axle & Steering System
The document discusses front axles and steering systems. It defines different types of front axles including dead, line, and stub axles. It also describes the four types of stub axles: Elliot, reversed Elliot, Lamoine, and reversed Lamoine. The steering system section covers steering geometry including camber, caster, king pin inclination, and toe. It also discusses Ackermann steering geometry and different steering gear boxes such as worm and sector, rack and pinion. In summary, the document provides an overview of front axle and steering system components and geometry.

Gas agency management system project report.pdf
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Coning of wheels
- 1. CONING OF WHEELS By : Swapnil Mangaonkar
- 2. Definition :- The surface of wheels are made in cone shaped at an inclination of 1 in 20 , and the same slope is provided in the rails. 20 1
- 3. Concept :- If the tread of the wheels are flat then there will be movement between wheel & rails due to which vehicle not be maintained in central position due to which there will be unequal distribution of load. To avoid that coning of wheels should be done.
- 4. How it works :- Straight track :- For smooth riding track should not touches the flange for that track should touch centre of the wheel and this insure by coning of wheels.
- 5. Curved track :- For outer wheels have to cover greater distance than inner wheel due to centrifugal force, due to coning of wheels diameter of wheels increases over outer rail and decreases over in inner rail.
- 7. Need:- • To reduce lateral movement of the axle • To reduce the contact between flange and inner side of the rail. • Smooth flow of the train on tracks is made possible because of coning of wheels
- 8. Disadvantages :- Due to centrifugal force , the horizontal components tends to turn out and rail has widening tendency If no base plate is used under void sleeper under the age of the rails are damaged. Pressure on outer rail is more than inner rail this result in wear of outer rail This disadvantages can be prevent by tilting of the rails.
