USES OF TURN TABLES IN RAILWAYS

What is the use of railway turn table?
In rail terminology, a railway turntable or wheelhouse is a device for turning railway rolling stock, usually locomotives, so that they can be moved back in the direction from which they came.
Where is a railway turntable?
Therefore turntables were predominantly situated at main train stations and in train depots, right by the roundhouse. The roundhouse enabled easy access to the individual locomotives' maintenance areas, which would otherwise only be possible by a complex network of switches.
Are railway turntables still in use?
The very first locomotives could only run in one direction, so a device was needed to turn them. Even with bi-directional trains today, turntables are still used as a convenient means for moving locomotives and other equipment onto tracks headed in the correct direction.
What is the principle of turnout in railway?
Turnout is an arrangement of points and crossings with lead rails by which trains may be diverted from one track to another moving in the facing direction. A turnout is left handed or right handed as the train taking the turnout in the facing direction is diverted to the left or right of the main line.
Why are turnouts important in railway?
Right-hand railway turnouts are used when trains need to switch from one track to another track that is on their right. Left-hand railway turnouts are used when trains need to switch from one track to another track that is on their left.
What are the parts of a railway turntable?
Some of the common components shown are:
  • Bridge Track: The section of track on the turntable bridge.
  • Bridge Rail: One of the two sections of rail that make up the Bridge Track.
  • Pit Rail: The circle of rail that lines the circumference of the turntable pit.
  • Pit: The below grade foundation the turntable is installed on.

NOTCHES AND WEIRs

Image
   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...

What are different diameters of steel used in construction field?

         In the construction industry, the appropriate selection of materials is crucial as they form            the fundamental basis for determining the strength and durability of structures. TMT (Thermo-Mechanically Treated) Steel is one of the essential components in construction as it stands out for its exceptional strength and ductility in building structures. Thus, contributing to the prolonged longevity and durability of the structures. In this article, we will delve into the different sizes of  TMT steel bars  and their different uses in the construction industry. These TMT Steel bars come in different sizes based on their varied diameters. The different diameter of steel bars are as follows: 8mm Steel Rod 10mm Steel Rod 12mm Steel Rod 16mm Steel Rod 20mm Steel Rod 25mm Steel Rod 32mm Steel Rod, etc TMT bars of varied sizes, play a pivotal role in diverse infrastructure initiatives, the versatility of TMT bars is ...
