what is HOG 7 Answers what is HOG May 09 2019 (17:48) Blog Post# 4312903-7 TouristerDivyanshu^~ Added by: SteelCityRF^~ May 11 2019 (01:08) WDP-4B 40001 (now BGKT) Having HOG ports Nopes no WDP4D is/was HOG capable..only some WDP4B were capable enough... Eg. 40084/40085 BGKT -> Regular links of HOG JP JU LHB ICE Eg.40079 PRATEEK -> Now HOG ports taken off... Only one experimental WDP-4D prototype is HOG fitted. Else only P7's and very few WDP-4B's are HOG capable. Edit: After some research, I've found that experimental HOG WDP-4D prototype is TKD WDP-4D #40110 HOG (Head-on generation) simply means that the electricity used for coaches (lighting, fans, A/C, pantry car cooking equipment etc) is generated by the locomotive. It is not related to electrification or OHE directly. In an electric loco, the power will come from the OHE. In a diesel loco, it will come from the diesel generator in the loco. In an electric locomotive, since the electricity is supplied by the OHE, a locomotive having a HOG feature simply has some equipment in it which converts the power received from the OHE into something... more... I believe 4-5 WDP4B locos were given the HOG feature (40001 being one of them). But IR never took the HOG feature seriously in diesel locos. For electrified sections, using HOG locos will help save diesel. But on un-electrified sections, it doesn't really make a difference as both the loco and EOG use diesel only. The HOG for diesel locos wasn't a failure, rather it was just not useful in the way they were doing it. Also, an E-loco can have a HOG feature without losing it's traction power. Since the power is drawn from the OHE, it can just draw the additional power from OHE while maintaining it's regular hauling power. For... more... 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... more... |
