Head on Generation (HOG) Technology Gains steam in SCR




- In the first phase, all but two trains (totalling 10 trains) having total LHB coaches and running end-to-end with electric traction have been converted to HOG

- Benefits: Financial savings (of Rs. 29.3 crores per annum in phase I) and strengthening environment conservation

******

Head o­n Generation (HOG), a state-of-the-art new technology that has been introduced recently in trains with LHB coaches and hauled by electric traction, is bringing in a transformational change in train running in terms of both financial savings (due to reduction in diesel consumption) and promoting environment (by reducing both air and noise pollution)

HOG technology can be introduced in trains with LHB coaches and hauled with electric traction. This technology caters to the power needs of the coaches such as coach lighting, Air conditioning, etc by substitutingthe earlier technology of having two power cars in the trains known as End o­n Generators (EOG).

In general, the power supply tapped from power lines throughpantograph to the train engine is used to run the engine and haul thecoaches. Now in this new system power supply tapped from overhead to the train engine will be distributed to the trailing coaches for power needs. This new system does not require any diesel oil consumption and as suchwill reduce air pollution and also noise pollution. In addition, it also provides uninterrupted illumination in the coaches.

Taking forward the implementation of new technology, Charminar Express running between Hyderabad - MGR Chennai Central - Hyderabad has also been provided with HOG technology from today i.e., 04th November, 2019. Earlier Charminar Express was running with traditional ICF coaches and electric traction power from end to end. Now the train is converted to run with LHB coaches paving the way for implementation of HOG technology.

With this in the first phase, all but two trains (totalling 10 trains) having total LHB coaches and running end-to-end with electric traction facility have been converted to HOG technology. In addition, o­ne more train with LHB coaches (i.e., Rayalaseema Express) running partly in diesel section has also been converted into HOG within the electrified section.

As such, the 11 trains running with HOG technology and LHB o­n SCR include Charminar Express (12759/12760), Vikrama Simhapuri Amaravati Express (12744/12743), Telangana Express (12723/12724),Tirupati – JammuTawi Humsafar Express (22705/22706),Double Decker Express (22708/22707), Narayanadri Express (12733/12734), Secunderabad - Nagpur Express (12771/12772), Secunderabad - Sirpur Khagaznagar Express(12757/12758), Secunderabad - Guntur (12705/12706), Lingampalli - Vijayawada Intercity Express (12795/12796) and Rayalaseema Express (12793/12794).

Earlier, the fuel consumption for these 11 trains per annum was around 49.7 lakh litres incurring a cost of more than Rs 35 crores. Whereas,currently the electrical energy consumption cost for these trains is o­nly Rs 5.7 crore per annum. Thus, the estimated savings for Railways o­n account of introduction of HOG in all these 11 trains comes to Rs 29.3 crores per annum.

Shri Gajanan Mallya, General Manager, SCR advised officers and staff to expedite the installation process of HOG compatible equipment in the Electrical locomotives and also replacing the existing ICF traditional coaches with all new LHB. Plans are o­n hand to introduce similar system in some more trains shortly to reduce the diesel consumption and also towards environment conservation. Accordingly, modification of electric locomotives and LHB coaches (to comply with HOG technology) and other steps are in fast progress.
