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).

- The discharge shall commence not less than 12 hrs. and not more than 24 hrs. from the completion of a full charge and the battery unit shall be discharged through a suitable resistance at a current I = 0.1xC10 ampere. C10 being the rated capacity. The discharge shall be stopped when the closed-circuit voltage across the terminals falls to 1.80 x n volts, where ‘n’ is the number of cells in series or until the voltage across one cell has fallen down to 1.75 volts.
- At this rate of discharge hourly readings may be taken until the battery unit voltage approaches 1.80V x n volts after which the readings shall be taken every 15 min.
- Two more discharge tests shall be carried out in accordance with Srl No 1 and the result of the test giving maximum AH capacity shall be taken as the 10 hrs. capacity.
- The battery unit shall be charged at a rate recommended by the manufacturer, immediately after each discharge.
- The capacity in ampere hours shall be obtained by multiplying the discharge current by the total time of discharge in hours and the product so obtained shall be corrected to a temperature of 27 deg. C by the following formula:
Ct
C27 = ————-
1 + R(t-27)
Where C 27 = Capacity at 27 deg. C
C t= Observed capacity at t deg. C
t = Average room temp. in deg. C
R = 0.0043 for 10 hr. rate of discharge.
The following method shall be used for determining the maximum ampere hour and watt-hour efficiencies.
- Ampere hour efficiency: A fully charged battery unit shall be discharged at I = 0.1 x C 10 ampere to a voltage
of 1.80 x n volts, careful measurements being made of the exact number of ampere hours delivered. On the charge the same number of ampere hours are put back at the same current. A second discharge shall then be made to the same cut off voltage as before. The efficiency of the battery unit is then calculated as the ratio of the ampere hour delivered during the second discharge corrected to the ampere hour put in during the charge. - Watt hour efficiency: The watt hour efficiency shall be calculated by multiplying the ampere hour efficiency by the ratio of average discharge and recharge voltages shall be calculated from the log sheets for ampere hour efficiency.
- Ampere-hour and watt hour efficiencies shall be not less than 95% and 80% respectively.
- The battery unit shall be charged at the normal charging rate. After charging, the battery unit shall be discharged for one hour at 10 hr. rate.
- The test shall be continued by increasing the discharge current to approx. equal to 1.5 times the value specified in Col.10 in Appendix-C (A1) and after an interval not exceeding 5 min., the current shall be decreased to half the value specified in Col.10 of Appendix-C (A2). The current A1 and A2 in amperes and the corresponding battery unit terminal voltages V1 and V2 in volts, shall be measured simultaneously.
The internal resistance expressed in milli-ohm of the battery unit under test shall be calculated from the formula given below:
(V2-V1)1000
R = —————–milli ohm
(A1-A2)
The internal resistance may also be measured by a direct reading meter of agreed to between the manufacturer and the purchaser.
The internal resistance when measured shall not be more than the value specified as for the respective class of diesel locomotives.
- After standing on open circuit for not less than 12 hrs and not more than 24 hrs. from the completion of a full charge, the battery unit shall be subjected to cycles of discharge at the rate of initial cranking current given in Appendix-C. Each discharge shall be of 15 secs. duration with an intermittent rest of 15 secs.
5.15.2 Requirements: The battery unit tested shall meet the minimum requirements specified as below
INITIAL CRANKING CURRENT TEST:
| Ambient temperature | Discharge current (15 sec with 15 sec rest) | Min no of such 15 secs cycles | Battery terminal initial at 5-7 secs | Final voltage (V) |
| 27 +/- 2 deg C | 1500 Amps | 8 | 1.1xn 8V | 0.80xn 4.4V |
| where n=no of cells in series per battery unit | ||||
- After standing on open circuit for not less than 12 hrs. and not more than 24 hrs. on the completion of full charge, the battery unit shall be subjected to a continuous discharge at the rate of sustained cranking current as given in given in Appendix-C.
- This discharge may not be taken immediately after initial cranking current test but may be preceded by one C10 discharge.

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.
