WR pioneers by running highest number of HOG converted trains over Indian railways

WR Saves More Than Rs. 32.22 Cr By Converting EOG LHBrakes Into Head On Generation (HOG) System In 2019-2020 & Rs. 83 Cr in the last 4 years

Western Railway is continuously working towards contributing extensively
to ‘Swachh Rail, Swachh Bharat’ Mission through new and ingenious ways. 
With an increased emphasis on reduction in operation cost of train and
providing a greener & cleaner environment, the Electrical Department of
Western Railway has commissioned 67 locomotives converted to Head On Generation
(HOG) System which the highest on Indian Railways.



According to a press release issued by WR CPRO Ravinder
Bhakar, Western Railway has commissioned 67  3-Phase state-of-the-art WAP7
locomotives in which 25 kV Over Head Power Supply is converted to 750V by 500
KVA converters installed in the locomotives and transmitted through electrical
couplers between coaches to meet electrical load of train. It is worth
mentioning that in the current financial year, Western Railway has modified
electrical circuits in 34 rakes which is the highest on Indian Railways by a
zonal railway. 



As on 20th January, 2020 out of the 65 HOG compliant LHB
rakes primarily owned by Western Railway, 51 LHB rakes are running in services
of 49 regular train pairs trains on HOG system. Efforts are being made to
facilitate further proliferation of HOG system and savings in cost of train
operation by expediting work of electrification on Western Railway.



Bhakar added that the HOG conversion work on Indian Railway
was first started in Mumbai Central Division of Western Railway in November
2015, when the first rake of Train no. 12951/52 Mumbai – New Delhi Rajdhani
Express was converted and taken over on HOG system. Since then the HOG rake
holding & locomotives has increased progressively. As a result, Western
Railway has recorded net savings of Rs. 32.22 cr during current financial year
2019-20 (upto 20thJanuary, 2020) and a total net saving during 2019-20 is
expected to be Rs. 45cr (approximately).



It is applaudable that due to the switching over to HOG
system, Western Railway has been able to achieve net savings of Rs. 83.06cr
since December 2015 to 20th January 2020. The savings is on account of lower
cost of electric energy drawn from overhead lines vis-a-vis cost of energy
generated by operating the DG sets installed in power cars. In addition to the
savings, there has been drastic reduction in the consumption of High Speed
Diesel (HSD) oil i.e. 16,696.843 KL which has led to reduction in CO2 emissions
by 44,080 MT & thus helped in making the environment cleaner and pollution
free.
