Jamshedpur: South Eastern Railway ( SER) has saved Rs 4.74 crore on fuel cost by introducing Head on Generation (HoG) system in operating trains.
In the HOG system power supply is drawn from Over Head Equipment (OHE) through converters provided in electric locomotives (WAP-7/WAP-5) for coach AC, lighting, fans etc. This system is being provided in long distance trains having DG sets provided at both the ends.
The system is considered to provide a cost effective, reliable and energy efficient supply system for coaches. This eliminates use of diesel alternator set in power cars which creates noise and air pollution. This system also helps in reducing carbon emission.
