MUMBAI (Metro Rail News): Mumbai Metropolitan Region Development Authority (MMRDA) has recently floated the tenders for the Metro 12 corridor, which connects Kalyan to Taloja for better Connectivity. Maharashtra’s Chief Minister, Eknath Shinde, has announced funding of Rs. 1521 crore for the project and stated that work on the ground would commence shortly.

This upcoming extension of the Mumbai Metro’s Orange Line (Thane-Bhiwandi-Kalyan) is the Kalyan-Dombivli-Taloja line. This new corridor will span over 20.75 kilometres, encompassing 17 stations, providing a convenient and seamless mode of transportation to and from the upcoming Navi Mumbai International Airport.

MMRDA has floated tenders for nine stations on the 20 km long line which will have a total of 17 stations. The cost of the contract’s first phase is Rs 780 crore. MMRDA expects to operate trains of 3 or 6 coaches in this area depending on the demand. Upon operationalisation, the line will be integrated with Mumbai Metro line 5, benefiting citizens of Kalyan-Dombivli, Ambernath, Ulhasnagar, Badlapur Thane, Navi Mumbai and Panvel in large numbers.

As per the Detailed Project Report (DPR), the corridor passes through agricultural and barren land with comparatively fewer populations. The main aim of this corridor is to accelerate development activities and promote the relocation of people from crowded parts of the city to this area, as stated in the DPR. The project also aims to decongest Mumbai city by providing an alternative commute option. The initial services on this route will be operated with three-car coaches and later introduce six-car trains. The route will have a total of 15 rakes. MMRDA anticipates around 1.25 lakh passengers in the first year and a daily ridership of more than 2.6 lakh by 2031.

PATNA ( Metro Rail News ): CBTC stands for Communications-Based Train Control, which is a modern signalling system used in the operation of Metro Rapid Transit System (MRTS) to help control the movement of trains. It is a wireless communication to transmit information between trains and the control centre. It is the latest technology available worldwide and is being adopted by all new MRTS networks in India. DMRC is also planning to utilize it in Patna Metro project in near future.

Here are some of the benefits of CBTC for the commuters:

Improved Safety: CBTC allows for real-time monitoring and control of train movements, which helps to prevent accidents and collisions. The system also automatically detects and reacts to any abnormalities or malfunctions in the train system, increasing the overall safety of the metro.

Increased Capacity and Efficiency: CBTC can increase the frequency and speed of train operations, resulting in faster travel times and more efficient use of the metro system. This allows for more passengers to be transported in a shorter amount of time, reducing crowding and wait times.

Reduced Maintenance Costs: CBTC systems can help reduce maintenance costs as the system constantly monitors and alerts the maintenance team to any potential issues or failures. This allows for preventative maintenance, reducing the likelihood of major failures or disruptions in train services.
Enhanced Passenger Experience: CBTC allows for smoother and more predictable train operations, which can improve the overall passenger experience. Passengers can rely on a more efficient and punctual service, and the system can also provide real-time information on train schedules and delays.

In conclusion, this system reduces headway (waiting period between two trains) and increases transport capacity. The technology relies on continuous two-way digital communication between each train and the control centre. Each train transmits its location, direction and speed to the control system which makes necessary calculations for safe travel.

The implementation of Communications-Based Train Control (CBTC) technology in the upcoming Patna Metro project is expected to revolutionize the way passengers travel in the city. Patna Metro is poised to become a world-class transportation system that will enhance mobility, connectivity, and quality of life for the people of Patna.

KOLKATA (Metro Rail News): On Tuesday, three companies, namely Larsen & Toubro, ITD Cementation India, and Afcons Infrastructure, placed their bids for the UGI underground contract of the Kolkata Metro Purple Line. The contract is for a distance of 5.05 km, between Mominpur and Esplanade.

In July 2022, Rail Vikas Nigam Ltd. (RVNL) requested bids for this contract, which had an estimated value of Rs. 2571.28 crore and an undisclosed deadline.

The last 15.215 km section of Line-3 (Joka – Esplanade), located in the northern region, will have two twin tunnels and four underground stations – Kidderpore, Victoria, Park Street, and Esplanade. The contractor assigned to this project will need to utilize two new tunnel boring machines (TBMs) and have one TBM on standby.

The Joka-Esplanade metro corridor in West Bengal, India requires the design and construction of a ramp and underground railway works covering a 5.05 km stretch (from chainage 9063.00m to 14113.00m). The scope of work includes four underground stations – Khidderpore, Victoria, Park Street, and Esplanade, tunnel construction through tunnel boring machines and cut & cover methods, architectural finishing works, track works, and more.

All three bids are undergoing technical evaluation, which is expected to take a few months to complete. Once the technical evaluation is concluded, the financial bids of the qualified bidders will be opened to identify the lowest bidder and the most likely contractor for this package.

It is anticipated that a contractor will be assigned to begin tunnelling work on this project in mid-2025, with the expectation of assigning the contractor in the second half of 2023. However, delays in the tendering process will likely result in this section not being operational until 2028. This extended timeline will result in the recently opened 6.49 km Joka-Taratala elevated section functioning as a disconnected stand-alone line for an extended period of time.

PATNA ( Metro Rail News ): The construction of the city’s new metro system is taking place with a focus on topsoil conservation. Delhi Metro Rail Corporation Ltd. (DMRC)understands the importance of preserving the fertile top layer of soil, which is essential for growing crops, plants, and trees. It is also a finite resource that can take hundreds of years to form but can be easily lost or damaged due to construction and development activities.

DMRC is taking a responsible and sustainable approach to the construction process by
implementing measures to minimize the impact on topsoil and promote its conservation. The topsoil is being carefully removed and stored for future use in parks, green spaces, and other landscaping projects within the city. Fertile topsoil is stripped to a depth of 20cm from the areas to be used for construction, and it is then stockpiled to a maximum height of 40cm in designated areas, covered or stabilized with temporary seeding for erosion prevention and then maybe reapplied to the site during the plantation of the proposed vegetation. It is also in line with the objectives of the Soil Conservation Act, which aims to promote sustainable land use practices and prevent soil degradation.

Saving trees during metro construction is another key aspect of DMRC’s commitment to
environmental responsibility and sustainability. During construction, it is important to
minimize the impact on existing trees and to replant new trees where possible. To achieve this, DMRC has implemented several measures, such as conducting a tree survey to identify and map the location of all the trees on the construction site, protecting them by installing barriers and providing appropriate care or translocating them someplace safe on need basis.

The DMRC is committed to ensuring that Patna Metro Project does not cause undue harm to the city’s tree population and is taking steps to ensure that the new metro facility enhances the city’s natural beauty and greenery.
