What Is The Role Of Traveling Ticket Examiners In Indian Railways?

Indian Railways, the world's third largest railway network, carries more than three million passengers a day.More than fifteen thousand trains run in Indian Railways every day,Indian Railways appoints ticket examiners on platforms and in trains to check the tickets of railway passengers.So let's see what the work of this ticket examiners......
There
...

are many tasks besides ticket checking mainly by ticket inspectors...
*The duties of a ticket inspector are as follows*
1)Make sure to no one travels without a ticket on the Mail Express.
2)The sleeper coach TTEs are required to report for duty half-an-hour before the scheduled departure of the train.
3)The ticket inspector must have his / her railway identity card, badge, proper uniform.
4)It is the duty of the TTE to allot berths/seats, which are vacant, to passengers at intermediate stations on realization of fare/surcharge as per rules on first come first served basis or according to the priority on the waiting list if such a list is kept at the station.
5)Make sure no one else is traveling in the seat reserved for women and the disabled.
6)He shall pay prompt attention to all complaints from passengers in regard to non-working of fans, lights, lamps, etc, and take necessary remedial action to get them rectified.
7)Take care of that no other passenger travels in an air-conditioned coach.
8)If any person is found traveling without a ticket, the appropriate surcharge / penalty should be recovered from him or the person should be charged under Indian Railways Act 137 and handed over to the GRP/RPF police.
9)The TTEs carry blank FIR forms for making them available to the passengers in case of any incident of theft of luggage, etc. Such forms duly filled in be handed over to the next GRP Post at the scheduled stoppage for further action in the matter.

What is the mechanism that stops the train when pulling the chain?
When you look in between two coaches you will see the coaches are coupled with the coupler, and there are two black pipes below the coupler. It continues from engine to rear of the train. One of those is Feed pipe, the other is Break pipe. Why? The feed pipe is connected with the engine's MR reservoir which maintains 5kg per sq cm air pressure from engine to rear to keep the breaks of coaches in release condition. The other the break pipe which exhaust the air pressure either it is applied by the driver or a passenger pulls the alarm chain. As soon as any of the one happens
...

break pipe pressure drops below 5kg per sq cm and break applies. If it is done by the driver instantly he will create 5kg pressure in feed pipe and feed pipe will feed the break pipe as much air pressure exhausted by the driver, and break will release, train will move freely. You must have experienced that during your journey, sometimes it is slow, and again normal speed.

Now, when someone pulls the alarm chain what happens. At the end of every coaches on top you will see a mechanism. Actually that is a valve, known as Clappet Valve. It is connected with the brake pipe. When someone pulls the chain this velvet opens and air pressure exhausts from break pipe. Since it is done from a coach, driver of the train can not maintain break pipe pressure required 5kg per sq cm from engine. So how to set. When the chain is pulled, Clappet Valve opens air pressure releases through the valve with a big hissssing sound. Until the valve is closed the break pipe pressure will not built up to the required and train will not move. Look at the valve, you will see a steel wire is hanging with a wooden handle. Staff of the train will come , will pull the steel wire and the valve will be closed. Hissing sound will stop. Within minutes feed pipe, and break pipe will maintain required air pressure, Breaks will be released and enjoy your onward journey.

What is the meaning of the WAP-4 type locomotive used in Indian Railways ?

WAP - 4 is a common used in India.

The locomotive was developed after a previous class
...

was found inadequate to haul the longer, heavier express trains (24-26 coaches) that were becoming the mainstay of the Indian Railways network. It was introduced in 1994, with a similar bodyshell to the WAP-1 class, but with Hitachi traction motors. Electricals are traditional DC loco type tap changers, driving six arranged in Co-Co fashion. This locomotive has proved to be highly successful, with over 750 units in service. Newer examples have been fitted with microprocessor-controlled diagnostics, static converter units (instead of arnos) and roof-mounted dynamic (rheostatic) brakes. The locomotive can be seen in service across the electrified network of Indian Railways and is homed at 14 sheds (depots).

The last locomotive produced by the Chittaranjan Locomotive Works (CLW) was numbered 25051 in December 2015 and production of this locomotive has been stopped.

Design

The loco has a streamlined twin cab carbody design, with top-mounted headlamps. The first 150 or so units had the headlamp mounted at waist level, with the lights being mounted in a protruding nacelle. Some earlier locos, especially from the Erode loco shed have the headlamps placed on the top. Later on the headlamps were placed in a recessed nacelle, and from road #22579 onward, the headlamps were moved to the top. Also they have digital notch repeaters.

Newer locos also feature larger windshields, more spacious driver cabin with bucket seats and ergonomic controls. The control panel also features a mix of digital and analog displays in newer units (all analog display in older versions).

Original units were weighed 120 tonnes, which was brought down to 112 tonnes through the usage of lighter material.

Some of the WAP-1 and WAP-3 and all the WAP-6 units were rebuilt to WAP-4 specifications after replacing the bogies & electricals.

It has different underframe for handling larger buffing loads. Some units are fitted with speed recorders and some changes to control electronics. Some units also have data recordersfor energy consumption. Some are even fitted with windshield washers and rearview mirrors. Few were provided with signalling lamps which were subsequently removed.

Technical variants include WAP-4E which are probably fitted with electronic sensors for sensing pipe pressure loss.

The Hitachi traction motors are the ones used on freight engines. It was a challenge to put these in a passenger engine due to weight constraints. So the transformer is aluminum foil-wound and aluminum chequered plates are used for reducing the weight.

415 volts, three-phase, 50 Hz power supply is used to drive various auxiliary motors like (1) Traction motor blowers (2) Transformer radiater blower (3) Transformer oil pump (4) Smoothing Reactor Blowers (5) Silicon Rectifier Blowers (6) Battery charger. The three-phase, 415 volt supply is obtained from the single phase supply by Arno converter or static converter.

Indian railways has installed microprocessor based fault diagnostic system and Vigilance Control Device for the enhancement of safety and reliability of electric Locomotives. Some of the newly manufactured WAP-4 locomotives also have air conditioning system for the loco pilot.

What is Auto-Emergency Brakes (AEB) in WDG4 Locomotives ?

Introduction :-
Auto-Emergency Brakes (AEB) refers to a special system of braking employed on some ghat sections with steep gradients, notably the Braganza ghat between Kulem and Castle Rock. With this system, the loco's speed is limited to 30km/h and the brakes are automatically applied if the loco moves faster than that at any
...

time on the AEB section.

Procedures :-
The AEB system is activated by means of a key obtained at the top of the descending grade (at Castle Rock for the Braganza ghat). The key, which is specific to each loco, is engaged and turned in the loco, and then removed and handed to the guard of the train (except for light locos where there is no guard). While the AEB system is activated, the loco cannot run faster than 30km/h; the brakes are applied immediately if the speed rises above that.

When the loco reaches the bottom of the down grade (Kulem at the foothills of the Braganza ghat), the AEB system is deactivated and the key is handed over to the Station Master of the station at the bottom of the ghat section (Kulem). From there onwards, the loco can proceed at normal permissible speeds.

The AEB key specific to a loco is handed over to the loco pilot by the Station Master of the station at the bottom (Kulem) when the loco is above to ascend the ghat section.

Operation :-
The AEB system depends on a speed sensor attached to the axle generator (tachometer generator) of the locomotive. The speed sensor controls the Emergency Brake Relay (EBR). The EBR gets energized when the speed sensor detects that the loco is moving faster than 30km/h (or other programmed speed limit).

When the EBR is energized, two emergency brake valves, EBV1 and EBV2 get activated.

The first emergency brake valve EBV1 cuts off pilot air from A9 to C2, with the additional C2 relay then causing the Brake Pipe to exhaust, while the second emergency brake valve EBV2 also exhausts the Brake Pipe pressure and causes application of the brakes.
