******** A Dedicated Blog On Rail Fastening System ******************
1 Fish Plate: In rail terminology, a fishplate, splice bar or joint bar is a metal bar that is bolted to the ends of two rails to join them together in a track. The name is derived from fish, a wooden bar with a curved profile used to strengthen a ship's mast.The top and bottom edges are tapered inwards so the device wedges itself between the top and bottom of the rail when it is bolted into place.In rail transport modelling, a fishplate is often a small copper or nickel silver plate that slips onto both rails to provide the functions of maintaining alignment and electrical continuity.
History of Fish Plate:
The first railway

fishplate, patented by William Adams and Robert Richardson in 1847.The device was invented by William Bridges Adams in May 1842, because of his dissatisfaction with the scarf joints and other systems of joining rails then in use. He noted that to form the scarf joint the rail was halved in thickness at its ends, where the stress was greatest.It was first deployed on the Eastern Counties Railway in 1844, but only as a wedge between the adjoining rails. Adams and Robert Richardson patented the invention in 1847,but in 1849 James Samuel, the engineer of the ECR developed fishplates that could be bolted to the rails.

Why are fish plates on a railway track called so?
Ans: A fish plate is a metal or wooden plate that is bolted to the sides at the ends of two rails or beams, to join them. A fish plate does not have anything in common with the aquatic fish. The fish in this term is derived from the French word 'fiche', meaning a peg. 'Fiche', in turn, is derived from the old French word 'fichier', which means to fasten. Thus a fish plate means a plate that fastens. This explanation has been given by

What is Rail Fastening System?
Ans: A rail fastening system is a means of fixing rails to railroad ties (United States) or sleepers (international). The terms rail anchors, tie plates, chairs and track fasteners are used to refer to parts or all of a rail fastening system. Various types of fastening have been used over the years.
Important Rail Fasteners are:
1 Rail spikes 2 Screw spikes 3 Fang bolts 4 Spring spikes 5 Fixing equipment
Important Rail supports are:
1 Chairs 2 Tie plates 3 Clips
There are Seven types of Rail Fastening namely:
1 Rail spike with baseplate above the tie
2 Track joint and chairs
3 Pandrol 'e-Clip' fastening
4 Pandrol 'fastclip' fastening
5 Tension clamp fastening
6 Bolt clamped fastening
7 Steel spring keyed rail in chair

********************** Types Of Wheel Arrangements and Axle Arrangements in Locomotives of Indian Railways ***********
All are requested please share views after viewing this particular blog.
Whenever you see the Technical Specification of any Locomotive, you find a term known as "UIC Classification". Take for example
The UIC Classification/Wheel Arrangement of WAP 4 is Co'-Co'
The UIC Classification/Wheel Arrangement of WAP 5 is Bo'Bo'
The UIC Classification/Wheel Arrangement of WAP 7 is Co'-Co'
The UIC Classification/Wheel Arrangement of WAG 9 is Co'-Co'
The UIC Classification/Wheel
...
Read more...
Arrangement of WAG 7 is Co'-Co'
The UIC Classification/Wheel Arrangement of WDM 3A/3D is Co'-Co'
In case of WDP 4 it is AAR wheel arr instead of UIC Classification which is B1-1B for WDP 4 and C-C for WDP 4B and 4D.
Now what does the term UIC Classification mean?
Ans: The UIC classification of locomotive axle arrangements describes the wheel arrangement of locomotives, multiple units and trams. It is set out in the International Union of Railways (UIC) "Leaflet 650 – Standard designation of axle arrangement on locomotives and multiple-unit sets".It is used in much of the world.
In other words UIC Classification is the Wheel Arrangement of Locomotives. If it is Bo'Bo it means the loco has two axles comprising of Four wheels in each axle in the front and in the rear side.(Total 8 wheels in the Loco) If it is Co'-Co' it means the Loco has two axle comprising of Six wheels in each axle in front and rear side.(Total 12 Wheels in the Loco).
For more details regarding UIC Classification its types please refer: click here
The term UIC stands for International Union of Railways to know more about International Union of Railways please refer:
click here
UIC classification is used widely in the world for all class of Locomotives.Only the United States uses the simplified AAR wheel arrangement for modern locomotives.United States don't use UIC Classification for the "Wheel Arrangement" of their modern Locomotives. In our Country also only WDP and WDG Class Diesel Loco use AAR wheel arrangement(As narrated above)
What is AAR wheel arrangement?
Ans: The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads. It is essentially a simplification of the European UIC classification, and it is widely used in North America to describe diesel and electric locomotives. In India this wheel arrangement is used for WDP and WDG Class of Diesel Locomotives. It is not used for steam locomotives which use the Whyte notation instead.
For more details about AAR Wheel Arrangement please refer: click here
For Steam Locomotives they use Whyte notation for their Wheel Arrangements.
What is Whyte notation?
Ans: The Whyte notation for classifying steam locomotives by wheel arrangement was devised by Frederick Methvan Whyte and came into use in the early twentieth century, encouraged by an editorial in American Engineer and Railroad Journal (December 1900). The notation counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, groups of numbers being separated by dashes.Other classification schemes, like UIC classification and the French, Turkish and Swiss systems for steam locomotives, count axles rather than wheels.In the notation a locomotive with two leading axles (four wheels) in front, then three driving axles (six wheels) and then one trailing axle (two wheels) is classified as 4-6-2.

Physics, Indian Institute of Technology Kanpur, NH-91, Kalyanpur, Kanpur – 208016, Uttar Pradesh.
Contribution for this case study:
This real time study of performance of WAP-4 of various Loco Sheds of Indian Railway with various trains like various Duronto, Rajdhani etc can't be possible without the contribution of Shri Bhawnath Jha, the loco pilot (Rajdhani) of ALD Division, NCR mainly experienced in hauling Rajdhani Trains also presented dozens of run time data sets in this Document of Case Study regarding WAP-4.
Objective of this Case Study of WAP-4:
In this work a strategy is being proposed for driving a tap changer controlled electric locomotive,specifically WAP4, which will result in the highest possible output performance while remaining within the tolerance limits of the voltage and current in the traction motors.
All members of IRI can know the following points from this case study of WAP-4
1 Why WAP 4 is withdrawn from the charge of some important Duronto and Rajdhani Trains and giving to WAP -7
2 Competitors of WAP-4 and their advantages
3 Driving Algorithms of WAP 4 for Loco Pilots to use the Loco to it's Full Potential for both LHB and ICF Coach Trains.(Separate Algorithms for LHB and ICF Coach Trains for the Loco Pilots using WAP 4)

Please note that this case study is based on the Personal Driving Experience of Shri Bhawnath Jha, the loco pilot (Rajdhani) of ALD Division, NCR mainly experienced in hauling Rajdhani Trains. So it is a very important Case Study I think to answer various issues regarding WAP 4.
This blog can answer all the questions regarding WAP-4 I think.

-------------------------------- Effective Service Life of the "Traction Motor 6 FRA 6068"used in WAG9 and WAP7 class of locomotives of IR----------------------------------
No where it is specifically mentioned that what is the "Service Life" of an Electric Locomotive after which the Locomotive needs to be scrapped. To know this particular answer I am posting this blog where you can find that the "Traction Motor" made by ABB(A Company of Switzerland) has a "Life Expectancy Period" of 30 years. So the Traction Motor 6 FRA 6068 which is made by ABB for WAG9 and WAP7class of locomotives of Indian Railways also has an "Effective Service Life" of 30 years.
