EOG stands for End-On Generation in Indian Railways. They are those railway coaches which are fitted with generators to supply electric power to the rest of the train. Therefore, an EOG is very important to ensure the seamless electric flow to the coaches, such as lighting, fans, and other critical services.
An End-On Generation (EOG) coach is usually mounted at either end of a train. It then provides a constant power supply throughout the train. EOG coaches derive power from diesel engine-driven generator sets (DG sets). Heavily utilised in the operation of electrical appliances for lighting, air-conditioning, cooling systems, and other onboard facilities. EOG coaches efficiently travel passengers in trains that do not have power cars or engines, complete with dedicated generators.
The following reasons are why the End-Of-Train (EOT) coaches are so important for railway systems nowadays. Primarily, the long-distance trains are supplemented with EOT coaches. They are neither fully powered by a dedicated engine nor an external source.
Power Supply: EOG coaches are endowed with generators that power several linked coaches, sustaining essential operating features such as lights, fans, air-conditioners, voice announcement systems, and others throughout the journey. Thus, it provides well-lit spaces for passengers no matter how long a trip takes.
Effective Energy Supply: The engine load is cut off by EOG coaches from the main engine since they draw power from all independent sources. The engine requires less time in the case and has less pressure compared with the use of full power. This feature adds to reliability and efficiency during long-haul travel.
Very Economical for Passengers Comfort: An induced amenity would be the presence of adequate lighting, ventilation, and closeness through air-conditioning as a result of EOG's continuous energising, which would keep the journey at ease. This takes away the travelling ordeal from passengers when travelling at night or for long distances.
The EOG coaches must be connected across the entire train for any interruption-free power supply. Depending on the configuration of the train, these coaches usually are end-fitted either at the front or rear of the train. Well, let's understand how these engines function in more detail:
Generation of Power: A generator in the EOG coach is powered by diesel fuel. The various systems that require electricity in a train are lighting, ventilation, and air conditioning, with that generator making provision for such. The engine runs on diesel, providing a continuous and reliable power supply during long travels and often interrupted journeys.
Power Distribution: When generated, it is distributed to a wired line for the other coaches of the train for the smooth functioning of all important services in train lights, fans, and communication systems during the journey. Again, it is with great distribution as well as safety for a smooth journey.
Backup Power Supply: An EOG coach is primarily meant to provide an emergency backup power supply. The EOG coach is capable of taking over in the event of a power failure from the prime power source, whether caused by the train engine or a grid power failure from outside. Such backup energy is used to assign the network lighting system, ventilation system, and any other essential system to function during the journey when all other power sources fail.
Most such trains are long-distance as well as mail express trains, which operate their EOG coaches for power throughout the train. EOG coaches have value when the power supply at distant stations is inadequate or when the use of dedicated power cars is not feasible, e.g., the locomotive does not have the necessary generators to support all coaches. Most Indian Railways trains are constituted with EOG coaches for continuous power supply. A few luxury trains may have even more premium amenities. They may be drawing power from special sources or systems, which are directed at improving onboard facilities to provide superior comfort to passengers.
Power Backup: Provides an uninterrupted power supply for long-distance journeys.
Fuel Efficient: The diesel consumption suffices while travelling.
Positioning: These are on both sides of the train which is also termed as 'End-On Generation'.
Passenger Wellness: Provides lighting, air conditioning, and other passenger amenities.
EOG coaches are the most indispensable part of their systems because they are very much able to satisfy the needs of users by providing uninterrupted power and safety during their journey. EOG coaches are vital for safe long-distance train travel. Additionally, they provide affordable and very dependable power for the trains in the country.
It actually means End-On Generation. It refers to a class of coaches that has diesel-powered generators that provide power to the entire train.
A train with EOG coaches will have a continuous power supply for lighting, fans, air conditioning, and other amenities in the coach.
EOG coaches normally will be found at the front or at the rear-most portion of a train to support the power requirements for the whole train operation.
EOG coaches are not available on all trains. These are found only in long-distance trains where additional power source provision is required for non-AC services.
No, EOG coaches have not been designed to seat passengers. It has been used primarily for power generation for all the other coaches on the train.
