Now At can least from the above statistics it can be possible said to that replace will dominate and will secure top position in the list in future with also p5/p7???
At least the above statistics said P4s will dominate in future also and will secure top position in the list

Body of the Report:
Abstract
Breakage of brake riggings in WAP7 locomotives has been a matter of concern since 2004, almost after its commencement of manufacturing, which is having same bogie design as that in WAG9 locomotives
Both of these bogies are having TBU/PBU assembly for brakes, but breakage of brake hangers in WAG9 locomotives are unheard off
Both the inner as well as outer hangers are breaking
However, the cases of breakage of inner hangers towards bogie frame are much more with 80% of the total failures
This paper deliberates to understand the various failures in locomotive Bogie Brake-Hanger and on root cause analysis for the failure of Brake hanger
In this paper we analyze the characteristics of brake hanger using FEA software
Introduction
Regardless of the remarkable increase in the train speed, trains need to be stopped safely within a
limited braking distance without causing any discomfort to the passengers
Currently, most trains are run by electrical power and have a combined electrical and mechanical
(friction) braking system
Breakage of brake riggings in WAP7 locomotives has been a matter of concern since
2004, almost after its commencement of manufacturing, which is having same bogie design as that in WAG9
locomotives
Both of these bogies are having TBU/PBU assembly for brakes, but breakage of brake hangers in WAG9 locomotives are unheard off
Both the inner as well as outer hangers are breaking
However, the cases of breakage of inner hangers towards bogie frame are much more which 80% of the total failures

WAG-7 Type Electric Locomotives
WAG-7 is an electric locomotive engine of Indian railways used to haul specially goods train and is maintained by Ajani Loco shed, Nagpur India
The Loco has six axles in two sets of three frontal and rear wheels
WAG-7 is the name of a type of electric locomotive shown in figure 1 used in India
Homed mainly At Gomoh, Ajni, Lallaguda, Tughlakabad and Bhilai
It is very similar to the class WAP-9; the only difference being the gear ratio which makes it suitable for heavy weight Operations
The technical specifications of WAP-9 type electric locomotive are mentioned in table 1
Table 1:
Technical Specifications of Electric WAP-9
Manufacturers ABB, CLW
Traction Motors
ABB's 6FRA 6068 (850kW, 2180V, 1283 rpm, 270/310A
Weight 2100kg) Axle-hung, nose-suspended
Gear Ratio 77:15
Transformer ABB's LOT 6500, 4x1450kVA
Hauling capacity 4250t
Wheel base 15700mm
Brake Hanger of Electric Locomotive WAG-7 and WAG-9
During a brake application, the brake beam on either side of a wheel set are moved by the brake cylinder through the brake rigging so that the brake block holders are pulled towards the wheel treads
The brake beam however only controls the movement of brake blocks in horizontal plane and provides no vertical restraint
The upper part of the brake hangers are connected brackets on bogie frame by the upper brake hanger-pins
Table 2: Technical specifications of Brake hanger

Observations
The problem identified in the assembly of brake-hanger of WAG-7 railway engine is that the brake-hanger fails
under fatigue
Following are the observations on failed brake-hanger
1
The brake-hanger usually fails during running condition after certain period
2
100% breakage at the top of the hanger plate
3
The initiation of crack begins near the bush welding which progresses and breaks the hanger plate into
two pieces
4
Both the inner and outer hangers are breaking but the breakage of inner hanger towards bogie frame is
much more with 80% of total failure
5
Failures in PBU (weight of 150 kg) are more compared to TBU (weight of 130 kg)
(It should be noted that, the material report confirms the brake-hanger material as per requirements
