HOG means Head on Generator!!!
this is actually used in most emergency purposes!!! only a 3 phase loco can transfer the power from over head wires to the EOG's n to the coaches!!!
After extensive trials and improvements on the design, commercial service of HOG scheme involving one 3 phase electric loco and 12 passenger coaches & two power cars have been started from 21.02.2011 between New Delhi-Kalka & back in train no. 12005/’06 NDLS-KLK Shatabdi Express. In this scheme the power supply is received directly from locomotive through couplers and
DG sets kept off to be used during emergency only. The supply from locomotive is 750V, 3 phase.
No noise (DG sets will not be used)
• Saving of HSD oil (about 700 Ltrs per round trip)
• Economical (saving of about 18,000.00 per round trip)
• Pollution free environment at Rly. station etc. (No smoke as DG sets will not be used)
this isnt introduced everywhere as of now!!! wil take sometime to hit the tracks!!!!
mostly few WAP-7's n WAP-5's have this 3 phase system as of now!!!!
