India Developing, but still a long way to go

Anti Collision Device (ACD).
View attachment 311580
Anti Collision Device (ACD)

  • Anti Collision Device (ACD) is a fully integrated Electronic Control System designed to minimize collisions and increase safety on Railway system.
  • It is a non signaling system and provides additional cover of safety in train operations to prevent dangerous train collisions caused due to human errors or limitations and equipment failure.
  • ACD system does not interfere with normal working of train operations.
  • Being the non-signaling and inter locking system it does not replace any existing signaling and interlocking system and does not alter any procedures of train operations in vogue.
  • Network of Anti -Collision Devices (ACDs) are provided comprising of a variety of devices such as onboard (Mobile) ACDs for Locomotives and Guard vans and track-side (Stationery) ACDs, Level Crossing ACDs, Loco Shed ACDs, Sensor based ACOs and ACO Repeaters. All these work on the principle of distributed control systems.
  • All ACDs along the ACDroute communicate with each other through radio communication when they are within a radial range of at least 3 kms. On board computers use inputs from Global Positioning System (GPS) for determination of train location, speed, course of travel and time.
  • Both mobile and stationary components of ACO system exchange information and take decisions based on train working rules and embedded software to apply brakes automatically without any input from the users.
  • If two ACOs are deemed to be at a risk of collision, the ACD system activates automatic braking operation to prevent collisions. Loco ACO is designed to interface with various types of braking system of locomotives.
  • System provides audio-visual "Train Approach" warning to road users at level crossings. At Manned LC Gates, when approaching Loco ACD detects "Gate Open" condition, the speed of the train/loco is reduced and kept under a pre-defined speed. Similarly, it can also provide warning and regulate speed in case of movements of land slopes in deep cuttings that are "sensed" through Inclinometer grids, embedded in such slopes.
  • More than 2,000 Anti Collision Devices have already been installed over 2,700 Route Kms of track on Indian Railway system out of which about 1900 Route Kms are on North east Frontier Railway and balance are on Konkan Railway. Further proliferation of this safety device on the balance BG network of Indian Railways is being planned.
Wasn't this system was already tested on the trains by Indian scientist B Rajaram. I saw a documentary in National geographic few years ago. Are these the same systems?

The documentary you saw, was probably Chris Tarrant's Extreme Railways episode on Konkan Railways. I saw the same on NGC.

Rajaram Bojji was a Konkan Railways engineer and credited with development of Anti Collision Device Indian Version.

The system was required as originally entire stretch of KR was a single track (From Panvel to Mangalore). Orignal system (named Raksha Kawach or Safety armor) was a radio based system. Later several modifications of this system have been done including use of GPS.
 
@anant_s Bro whats the update on Talgo trial?
Next stage trials on new Delhi Faridabad section at 180 kph (North Central Railways) are planned later sometime in July.
As of now people who have tested the trainset on Izzatnagar division have high praise, especially with respect to the ride quality.

Ah, right. I thought it was supposed to be done on the Mathura-Palwal section around June end? Delhi to Faridabad is just around 25Km right? How do they plan on doing high speed test on such a small stretch?

Initial trials are to see ride quality and coach stability. the section is relatively straight and will be an in and out dash from Tughlakabad onwards. Presently they shouldn't have any problems to run train at upto 180 kph right upto Agra Cantt, but super saturation on this route means they can try only upto Palwal (3 line section). Once that is done, after safety clearance, final 200-210 trials on NDLS Kota mumbai Section will be conducted.
PS: Some premium trains (like Rajdhani) are already clocking 140 kph right after Kota towards Delhi, so it looks railway has already done its preparatory work on section for TALGO.
 
@Abingdonboy You asked what locomotives will ply on DFC sections getting commissioned with high rise OHE, prior to arrival of HHP IGBT locomotives, well here is the answer.
----------------------------------------------------------------------------------------------------------------------------------

Dedicated freight Corridors will feature a unique High rise Over Head Electrification (OHE) designed fro 2x25 kV Single Phase AC operation. for this India is deploying unique high rise OHE system which will have conductor (or contact wire) at height of 7.53 meters from rails in place of existing 5.8 meters.

The new generation IGBT based locomotives (both WAG 10&11 rated at 7 and 9 MW respectively) will have native design to travel under any kind of catenary (normal and DFC) but for existing locomotives (WAG 7 and 9), new pantographs have been fitted with newly developed WBL 85 HR and ABOH pantographs, that will allow locos to travel both on conventional and DFC tracks.

ABOH pantograph (Stone India) used on WAG 7 27982 (shown above).
 
To be frank, Mumbai buildings don't look great, sometimes even ugly, at least the older ones. I am not sure if it is because of closed economy and licence permit raj and useless rules and guidelines or is it because most builders are Gujjaratis, Marwadis, Sindhis, Punjabis etc (with finance of Muslim underworld too) and makes me suspects the so called architects are just rich pampered useless kids and relatives of these same people with fancy foreign degree.

If I compare the photos of other cities in India developing thread, other cities buildings exterior design look much decent compared to Mumbai, at least to my prejudiced eyes.

Nowadays there is this disgusting fashion of naming all the new buildings with strange english and european words. Is that supposed to be something exotic? I just see the elitist bias of anglicized generation pretending to be whites looking down on backward natives.

By now Mumbai should have had its own architectural style based on traditional local architecture and climate.What we have so far is irregularly shaped flat roofed blocks that are completely out of sink with local climate. Maybe because Mumbai is city of migrants and most of Mumbai construction sector is controlled by Kutchi-Jain cartel. And Gujarat and interior Maharashtra like much of interior India is water scarce with little rain and very hot summer. So the traditional homes in interior are flat roofed, often made of wood and mud (though now everything is becoming concrete).

So buildings in Mumbai leak in rains. Thank Eru Iluvatar, nowadays many housing societies are getting their roofs covered with some kind of canopy as an afterthought.

This how traditional homes in the konkan region look like:

They have roofs like that for a reason. Local architecture evolves around local climate and customs. The kind of torrential rains western coast gets is unique.

We need architects who can evolve these kind of roofs and other traditional elements like balconies/gallerries, large common verandah from tradional houses/havelis/wadas and mate it with modern designs.

I notice some buildings in Kochi attempted to use such rooftops. Don't they look nice?

Hope at least now Mumbai developes it's own modern architectural style.

Finally
Delhi Govt. Approves Delhi Metro Phase 4’s DPR
15 Jul 2016 ⋅ by TMRG ⋅ in Delhi Metro4 Comments
Note: At the time of publishing this post, the Delhi Government has not released an official press release (visit PR page). The author of the HT article which first broke this news has based his entire piece on a verbal confirmation from Delhi’s Transport Minister Gopal Rai and we all know what that can imply. All other articles out there (TOI, BS) have been copied over from a PTI report with no independent fact-checking.

As per all of these reports, the Delhi Government in a recent meeting has approved the Delhi Metro’s Phase 4 project’s Detailed Project Report in its original form with just 1 minor tweak. This comes after Delhi Metro Rail Corporation officials made another presentation to the Delhi Government in June in which it left it up to the Chief Minister to decide the final routes and whether to entertain changes proposed by some MLAs.

One of the significant changes made since January is the deletion of the 18.6 km Dwarka – Prem Piao line through rural north-west Delhi which the Delhi Government was trying to push the DMRC to build. The minor tweak to the DMRC’s original DPR is the inclusion of a 2 km extension of the Tughlakabad – Aerocity line up to the Magenta Line’s IGI Terminal 1 station.

Metro Lines
We’re now back to the original 6 corridors which add up to 105.93 km of which roughly 35 km is expected to be built underground. The total number will go up if and when new proposals in Gurgaon & Kundli (see details) and Ghaziabad (see details) are approved.

Extensions:
Rithala – Narela (Red line) – 21.73km
Type: Elevated
Stations: Rohini Sector 26, Rohini Sector 31, Rohini Sector 32, Rohini Sector 36, Rohini Sector 37, Barwala, Put Khurd, Bawana Industrial Area – 1, Bawana Industrial Area – 2, Bawana, Bawana JJ Colony, Sanpath, New Sanath Colony, Anaj Mandi and Narela

Janakpuri West – R.K. Ashram (Magenta line) – 28.92km
Type: Elevated & Underground
Stations: Krishna Park Extn, Keshpur, Meera Bagh, Paschim Vihar, Peeragarhi Chowk, Peergarhi, Mangolpuri, West Enclave, Deepali Chowk, Madhuban Chowk, Rohini East, Prashant Vihar , North Pitampura, Haiderpur, Mukarba Chowk, Bhalaswa, Majlis Park, Azadpur, Ashok Vihar, Derawal Nagar, Rajpura, GG Sabji Mandi, Pulbangash, Sadar Bazar, Nabi Karim and RK Ashram Marg

Mukundpur – Maujpur (Pink Line) – 12.54km
Type: Elevated
Stations: Burari Crossing, Jagatpur Village, Surghat, Khajuri Khas, Bhajanpura, Yamuna Vihar and Maujpur

New Lines:
Tughlakabad – IGI Terminal 1 (22.20 km) – shown in Moss Green
Type: Elevated & Underground
Stations: Tughlakabad, Tughlakabad Railway Colony, Anandmayee Marg Junction, Tigri, Khanpur, Ambedkar Nagar, Saket G Block, Saket, Lado Sarai, Mehrauli, Kishangar, Masoodpur, Vasant Kunj (Sec-D), Mahipalpur, Delhi Aerocity and IGI Terminal 1

Lajpat Nagar – Saket G-Block (7.96 km) – shown in Moss Green
Note: This line will be a spur/branch of the Tughlakabad – IGI line
Type: Elevated
Stations: Saket-G Block, Sheikh Sarai, Chirag Delhi, GK-1, Andrews Ganj and Lajpat Nagar

Inderlok – Indraprastha (12.58km) – shown in Aqua
Type: Underground
Stations: Inderlok, Dayabasti, Sarai Rohilla, Ahmal Khan Park, Nabi Karim, New Delhi Delhi, LNJP Hospital, Delhi Gate, IG Stadium and Indraprastha

Maps
Here are 2 maps which show the alignment of all the lines. Both maps have been embedded into the post to allow you to zoom in/out and explore for yourself!


By Phase: Phase 1 | Phase 2 | Phase 3 | Phase 4


Next Steps
After the Delhi government’s official sanction, the proposal will be sent to the Central Government for its approval. The DMRC is yet to reveal the funding pattern for this phase andhasn’t accepted JICA’s revised policy of a step loan in which key equipment will have to be procured from Japanese companies.

If you’ve followed the Delhi section of the site, you already know there’s a long way to go for commercial operations on Phase 3’s new lines to begin. As such, I’m expecting the DMRC to begin Phase 4’s tendering/bidding stage for construction only in the year 2018.
