High-speed Rail in India - Current Effort To Increase Speed To 160-180 Km/h

Current Effort To Increase Speed To 160-180 Km/h

For the first time in the history of Indian Railways,it aims to increase the speed of passenger trains to 160–180 km/h on dedicated conventional tracks.

The railway minister said in 2012 that a combination of prudent investment decisions in the areas of track and bridges, signalling, doubling and train-sets is proposed to be adopted to enable train running at speed of 160 kmph and above. The proposal would significantly reduce travel time for passenger trains by 20-25%. Such infrastructure would also enable Railways to run Shatabdi trains on long distance trunk routes and between metros, he said in his speech.

Approach to high-speed

Indian Railways' approach to high-speed is incremental improvement on existing conventional lines for up to 160 km/h, with a forward vision of speed above 200 km/h on new tracks with state-of-the-art technology, such as Shinkansen/TGV/etc. While they do not define high-speed, Indian Railways' approach matches the high-speed definitions of the Trans-European high-speed rail network, for upgraded lines and new lines built for high-speed.

Dedicate tracks to passenger trains

Dedicate tracks on existing trunk lines to passenger trains, by building separate corridors for freight trains, and build separate tracks for busy suburban traffic in Mumbai and other cities where traffic is equally busy. Without slower freight and suburban traffic, fast-express trains can run at the speed limit of rolling stock, the track or railroad switch, whichever is lowest among those that apply.

Upgrade tracks for 250–300 km/h

Upgrade the dedicated passenger tracks with heavier rails, and build the tracks to a close tolerance geometry fit for 250–300 km/h. This implied that the high speed gauge is 5 ft 6 in (1,676 mm) Indian gauge (broad gauge). High-speed tracks to be maintained and inspected using automation to ensure required track geometry. Perform more frequent inspection to ensure high confidence of safety at high-speed.

Design, manufacture and deploy railroad switches, with thick web construction and movable crossings that permit 50 km/h to alleviate this bottleneck to speed.

Upgrade locomotives and coaches

Improve coaches, which can support 160 km/h, with stainless steel bodies and crash-worthy designs, incorporating passenger and crew protection, and fire-retardant materials. Equip coaches with electro-pneumatic brake systems to enhance safe operations at 160–180 km/h.

Develop locomotives with output of 9000 to 12000 hp for hauling of 24-26 coach long passenger trains to 160–200 km/h.

Indian railways has asked IIT Kharagpur to conduct research to obtain the technological knowhow to increase the maximum attainable speed to 200 km/h. The project, which will be conducted in the Railway Research Centre of IIT Kharagpur, has four main goals; improving speed, improving carrying capacity (heavy haul), use of advanced material, advanced signalling and maintenance for better safety. The research is expected to be completed by the end of 2015.

Famous quotes containing the words current, effort, increase and/or speed:

    The current of our thoughts made as sudden bends as the river, which was continually opening new prospects to the east or south, but we are aware that rivers flow most rapidly and shallowest at these points.
    Henry David Thoreau (1817–1862)

    Writing fiction is ... an endless and always defeated effort to capture some quality of life without killing it.
    Rose Wilder Lane (1886–1965)

    It shows nobility to be willing to increase your debt to a man to whom you already owe much.
    Marcus Tullius Cicero (106–43 B.C.)

    Among the laws controlling human societies there is one more precise and clearer, it seems to me, than all the others. If men are to remain civilized or to become civilized, the art of association must develop and improve among them at the same speed as equality of conditions spreads.
    Alexis de Tocqueville (1805–1859)
