What is end on generation?

End on Generation in Railways (EOG) is the system used on fully air-conditioned Rajdhani and Shatabdi trains. The system comprises two power cars per train. Each power car has two DG sets and each DG set is rated at 300 kW. These are mounted inside the power car or the entire power car coach which is dedicated to these power plants. The power generated by these DG sets is utilized for electrical loads of the train.

What is EOG in train? Why end on generation is provided?

In EOG system, the electrical load (i.e. load of lights, fans and air conditioning, pantry etc. referred to as “Hotel Load”) in the coaches of Rajdhani and Shatabdi Express trains are fed from the power cars placed at either end of the rake. Each power car is installed with 2 Diesel Alternator (DA) sets generating a 3-phase (4 wires) power supply of 750 Volts 50Hz and the same is transmitted to the entire rake through two parallel cables feeders termed as Feeder-A and Feeder-B, running through the whole length of the train. This electric power supply is tapped at each coach through a 50 KVA transformer in Conventional Coaches and 60 KVA transformers in LHB coaches and is converted to 415 volts for feeding the equipment working at this voltage and further transformed down to 110-volt AC single-phase for feeding the equipment working at that voltage.
415 V, 3-phase supply is directly used for compressor motors, the condenser fan motors and heaters installed in the evaporator. The evaporator blower motor is fed at 110V, 3-phase ac. 110V ac supply is also provided for lamps and fans by connecting them between line and neutral on the secondary side of this transformer. Since the power cars are placed at either end of the rake, the system is termed as End on Generation (EOG).

Battery Mistakes All End on Generation battery Owners Need To Avoid!

Do not mix new batteries with old batteries

Railway End on Generation Battery reconditioning: often reconditioning an old starter battery can become quite a costly affair if you keep replacing dead batteries one by one; even the new battery will drain out rapidly as the old batteries tend to draw more out of the new one. 

EoG power car replacement batteries: It is best to have an expert from the company visit you to have a thorough inspection of the EoG batteries after a complete charge, compare the cell voltage, specific gravity to decide the state of charge & whether in needs to be replaced at all.

Avoid any sort of additives or desulfation methods

How to recondition End on Generation batteries? EoG Batteries are electro-chemical devices. All chemicals have a half-life period beyond which regeneration with chemical additives or desulfators for batteries have little effect if any temporary. 

The normal mode of failure of End on Generation batteries is usually due to grid corrosion if the lead alloys are not designed properly. Desulfators cannot repair corroded grids.
