Air springs use compressed air inside a rubber bellow to provide suspension for coaches. This allows the coach to maintain a constant height regardless of passenger load. Air springs were introduced for hybrid coaches because heavy passenger loads would compress main springs and damage coil springs, compromising passenger comfort. The air spring system uses a height monitoring valve to add or release air as needed to maintain the required buffer height. When loads change, the air spring initially adjusts its distance from the coach body and then the valve adjusts air pressure until the proper height is reached. Maintenance of the air spring system requires trained staff and spare parts available at stations.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

2. A schematic layout of rake test rig (RTR) is shown in. A rake of wagon stock can be tested with
this Test Rig. This Rig may also be used for testing the train in yards before attaching the engine.
The Rake Test Rig unit consists of air supply system and mobile test rig. The details are provided
in Annexure-I The mobile test rig is having a cubical structure and is mounted on wheels. It can be
taken to the yards and sick lines. The procedure is as follows:
A. Carry out Visual Examination of rake.
B. Prepare Test Rig for Rake Test.
C. Conduct Leakage, Service Application and Release Test. Visual inspection is a check of air
brake sub-assembly for any damage on the brake pipe, hose coupling etc and then rectifying
it. The steps are :-
i) Inspect loose suspension brackets and anti-pilferage devices of all air brake sub-assemblies.
ii) Visually inspect for any defect/damage in the brake pipe, hose pipe, coupling etc.
iii) Rectify or replace the problematic part/sub-assembly.
Procedure of Rake Testing for Freight Stock
Rake Test :
3. Rake Test can be performed by using a portable device called „Test Rig‟ or by Locomotive.
The Test Rig provides all facilities like locomotive to conduct the test. The source of
compressed air supply to the Test Rig is through a compressor installed in the wagon depot
for Brake Pipe and Feed Pipe of the test rig. The Air Dryer should also be provided just
before connecting brake pipe and feed pipe for air supply system and Mobile test Rig.
Attach the rake test rig to the rake through the couplings. Carry out following tests as per the
procedure given in G-97 Annexure-XI {MP guide No.11 (Rev.01) amendment No.01 of Jan-
2010} for checking capability of locomotives for Charging/Releasing of train brakes,
checking of leakage in the train, checking leakage in feed pipe, brake cylinder operative
percentage, and procedure to be followed at way side.
4. Following examination must be carried out before rake testing
Hand Brakes of all wagons are fully released.
Operating handle of empty load box is in correct position i.e. 'Empty' position when
wagon is empty or lightly loaded and in 'Loaded' position when wagon is loaded beyond
the specified value.
Hose couplings of brake pipe & feed pipe on consequent wagons are coupled to one
another to form a continuous air passage from the locomotive to the rear end of train.
All the angle cocks except those at the rear end of the train are kept OPEN.
Hose coupling at the rear end of the train is placed on hose coupling support.
Isolating cocks of Distributor Valve on all wagons are in OPEN position.
5. Checking of Continuity and Leakage in Rake:
A. Attach the Diesel/Electric locomotive/Test Rig to the rake fitted with twin pipe air
brake system and couple brake pipes and feed pipes. Ensure correct coupling with
brake and feed pipe in a manner that there is no leakage of air from coupled joints.
B. The coupling should be done with angle cocks in closed position.
C. Open the angle cocks of loco after coupling feed pipe and brake pipe.
D. Open the angle cock of the brake pipes and the feed pipes on all the wagons and
check for continuity and leakage of brake pipe and feed pipe by reducing and
rebuilding brake pipe and feed pipe pressure operating by A9 brake valve & angle
cock fitted in feed pipe on locomotive (on wagon side) respectively. The verification
should invariably to be carried out through the pressure gauges (BP& FP) provided in
Guard's Brake Van.
6. NOTE: If the pressure is not within specified limit as given
above then check for leakage in rake and correct it.
7.
8. Leakage Rate Test:
E. After the stabilizing pressure as given in above table, move the driver's automatic
brake valve handle (A-9) towards application position to reduce brake pipe pressure
from 5.0 kg/cm² to 4.0 kg/cm².
F. After the brake pipe pressure has been stabilized –
i) Close the brake pipe isolating cock provided between additional C2W Relay valve
and brake pipe of the locomotive or isolating cock of Test Rig for checking BP leakage.
ii) Close the isolating cock provided between feed valve and feed pipe of the locomotive
or isolating cock of FP for checking FP leakage.
G. Wait for 60 sec for temperature and gauge settlement then note the drop in pressure
in brake pipe & feed pipe pressure gauge in locomotive for 05 minutes.
H. The drop in brake pipe & feed pipe pressure gauge shall not be more than 0.25
kg/cm²/min. If the leakage rate is more than the value indicated in (H), check for
excessive leakage on individual wagon as indicated below –
9. 1. A hissing sound would be audible at points where leakage is heavy.
2. Once the hissing sound is heard from a particular area, pin-point the location of leakage by
applying soap water solution.
3. Use permitted material viz. Teflon tape for arresting the leakage.
I. In case leakage is heavy and cannot be arrested, the wagon may have to be isolated/detached.
J. In case where leakage can be arrested temporarily by tap and the nature of leakage is such
that it requires attention at primary depot, clear marking on the wagon should be done to draw
attention of primary depot for adequate attention.
K. In case the leakage is from the distributor valve and cannot be arrested, isolation of the
wagon can be carried out by closing the distributor valve isolating cock. In such condition, clear
marking should be provided on the wagon to indicate this defect to primary depot. Do not close
brake pipe angle cocks under any circumstances, either for isolation of wagons or for any
purpose whatsoever, except for carrying out shunting operation after which the angle cocks
should again be opened to ensure continuity of brake pipe.
10. Service application and Release Test:
A. Move the driver's automatic brake valve handle (A-9) towards service
brake application position and drop the value of brake pipe pressure (BP)
between 1.3 to 1.6 kg/cm².
B. Brakes of all wagons should apply after brake application and brake
blocks on wagons should firmly grip on the wheel tread.
C. Check the piston strokes of all wagons. All Piston strokes should be
within the specified limits for different types of wagons. The piston
strokes are given below in table.
11. If the piston stroke is incorrect then, record “A” Dimension, it should be 70 ±20 mm in
empty and loaded condition.
D. Check all brake cylinders. Wagons with in-operative brake cylinders should be
marked unfit and detached.
E. After the release of brake, the piston of brake cylinder should be fully inside and
brake blocks
are free from the wheels.
F. Guard‟s emergency brake valve: Ensure that Guard Emergency brake valve is
working properly by operating it.
G. BPC (Brake Power Certificate): Ensure that Loco Pilot, Guard and TXR have
checked the details given in the certificate and signed for its compliance.
