Kolkata Metro’s East-West Corridor Gearing Up for Unmanned Operations 

KOLKATA (Metro Rail News): Kolkata Metro is going to adopt an Automatic Train Operation (ATO) System between Salt Lake Sector V to Sealdah stretch of East-West Metro.   

Clearance form CRS 

Necessary clearance from the Commissioner of Railway Safety (CRS) has been received for commissioning this system o­n this stretch. 

CBTC System 

East-West Metro Corridor is equipped with a Communication Based Train Control System (CBCTC).  This system consists of Automatic Train Protection (ATP), Automatic Train Operation (ATO) and Automatic Train Supervision (ATS) facilities.

ATO 

ATO consists of two systems viz. o­n-board and wayside ATO system. The salient features of the ATO System:

  1. It enables automatic braking, motoring, coasting, and stopping of the train within the specified speed profile. 
  2. When opted for ATO mode, the train accelerates, decelerates, controls and arranges motoring activities automatically.
  3. It ensures accurate stopping at the platforms and automatic opening of correct side train doors and Platform Screen Doors (PSD).  The responsibility of closing train doors, PSD and starting the train rests o­n the Motorman. 
  4. ATO operations ensure less power consumption and enhanced passengers’ comfort via optimum selection of acceleration and deceleration with controlled characteristics.

In ATO mode, Metro will move from o­ne station to the next station automatically after the long press of the ‘ATO Departure’ push button by the Motorman.  Train doors and PSD will open automatically after arrival at the next station.  The motorman will press the ‘Door Close’ push button on the respective side to close the train doors and PSD before starting the train.

Enhanced Safety 

Unmanned Train Operations (UTO) ensure the highest safety standards by eliminating human errors in traditional metro systems. With automation, UTO guarantees consistent train operations, reducing the risk of accidents due to factors like driver fatigue and distractions.

Enhanced Efficiency 

UTO not only enhances safety but also boosts efficiency. Automated systems maintain uniform speeds, providing a smoother ride experience, reducing wear and tear, and increasing train frequencies. This efficiency accommodates growing passenger demand during peak hours without requiring additional infrastructure investments.

Noida Sector 62 To Sahibabad Metro Gets A Boost With The Submission Of Revised DPR 

NEW DELHI (Metro Rail News):  The Delhi Metro Rail Corporation has submitted the revised Detailed Project Report (DPR) for the metro link between Sector 62 and Sahibabad to the Ghaziabad Development Authority (GDA).

Cost Escalation

Among the revisions made in the DPR, the most significant one is the escalation in the cumulative total cost of the project. The cost has risen from ₹1,517 crore to ₹1,873.31 crore, marking an increase of approximately ₹356 crore.

Land Requirement

The updated DPR indicates that the construction of the proposed Metro link will necessitate 7,690.10 square meters of private land and 19,001.2 square meters of government land.

Stations

Within the revised report, the Delhi Metro Rail Corporation (DMRC) has proposed plans for five stations along the 5.017km link. These stations are planned to be situated at Vaibhav Khand, near DPS Indirapuram; Shakti Khand; Vasundhara Sector 7; and Sahibabad.

Further Process

The revised DPR will now be sent to the board and later to the state government for approval. The revised DPR has also suggested a funding pattern of 20% and 80% for the central and state governments, respectively. The final funding pattern will be decided by the state government after careful consideration of the project specifics.

 GDA’s State

GDA is currently facing a fund crunch and has requested the state government to consider sharing the cost with a few other agencies, besides UP Awas Vikas & GDA.

 Sahibabad – A Strategic Location:  

The proposed metro link aims to connect Sahibabad, which is gradually becoming a strategic location due to the presence of an RRTS station and a multi-modal transit hub. With an RRTS station in Sahibabad, it is expected to become a hub for development and connection for the entire NCR.

 A Much-Needed Metro Link:  

The metro link between Sector 62 and Sahibabad is a long-awaited demand of the residents. The convenience and ease that metros offer to daily commuters necessitate the need for such a link.

Country’s First 31-meter U-girder Successfully Cast for Bangalore Sub-Urban Railway Project

BANGALORE (Metro Rail News): A 31-meter long, single-span U-girder, has been successfully cast for the first time in India for the Bengaluru Suburban Rail Project at Casting Yard, Devanahalli. 

For the Mallige Line 

It is an important milestone in the construction of the Bengaluru Suburban Rail Project. The ‘Mallige’ line or Corridor 2 includes the construction of around an 8 km viaduct or elevated section, from Hebbal to Yeshvantpura, using such U-girders.

First Time in the Country 

Countrys First 31 meter U girder Successfully Casted for Banaglore Sub Urban Railway Project 01 1

Applauding the feat, Dr M.B Patil, Hon’ble Minister for Heavy & Medium Industries and Infrastructure Development, Govt. of Karnataka said “It’s a momentous occasion that a single span 31-meter-long pre-tensioned U-girders has been successfully cast here in Bengaluru, for BSRP. It is the first time in the country that such a 31-meter U- girder will be used for rail-based transport infrastructure. I have always believed that the Bengaluru Suburban Rail Project with its many innovations, is not just going to be a game changer for Karnataka but will also change the way we visualise commuter rail travel.”

What are U-Girders? 

U-girders are U-shaped, pre-tensioned, precast girders that allow the track to be laid right away. U-girders are widely used in metro projects all over the world since they not only ensure superior quality but also save construction time. 

Countrys First 31 meter U girder Successfully Casted for Banaglore Sub Urban Railway Project 02

General Practice 

So far, 28- meter-long U- girders have been used in other metros. These girders are cast in the yards and will be transported to the location and launched over piers using high capacity Cranes/ launchers. It requires careful planning and accuracy to cast these U-girders in casting yards, away from the cities.

Specifications of the U-Girder 

Below are some technical descriptions for the pre-tensioned 31m U-girder:

  • One U-girder requires 69.5 cubic meters of concrete
  • M60 grade concrete
  • One U-girder weight: 178 tonnes
  • Corridor 2 alone requires 450 such U-girders.
  • Designed for Codal provision applicable to Indian Railway and Metro construction.

A solid Teamwork 

An engineering marvel, this 31m U-girder has been designed by Assystem STUP for BSRP and proof-checked by IIT/Madras. Third-party design evaluation has been done by a General consultant (JV of Egis, Aecom and WSP). Entire supervision, precision execution, and quality control were closely monitored by KRIDE to ensure that technical parameters were as per the approved structural design, before and during concreting, also extreme caution was exercised in the casting yard.

Countrys First 31 meter U girder Successfully Casted for Banaglore Sub Urban Railway Project 03

Efficiency at its Peak 

While box girders feature multiple segments between two piers which are post-tensioned, one single-span U-girders spans between two piers. As opposed to the six to seven days required for segmental construction, one single-span U-girder between two pillars can be built in a single night. The segmental box girder weighs much more than the entire span of a U girder. Unlike box girders or I-girders, track laying on these girders can be done right away. The use of a 31-m single span will reduce the number of piers, and foundations as compared to 28-m girder and save time for completion of civil works.
