Power Supply & Traction Works Requirement for Pune Metro completed

18/10/2022

PUNE (Metro Rail News): The Metro Train runs on electricity and is therefore an eco-friendly urban transport mode. A large amount of electricity is required to run metro trains. Carrying out structural works related to uninterrupted power supply for Metro is a challenging task. In the near future, a large number of passengers will travel by metro, so it is important to provide a continuous power supply for 17 to 18 hours of metro service and related facilities.

Recently, Pune Metro has completed the power supply work required to run the metro along the entire 33.2 km route. For continuous power supply, MSEDCL (Maharashtra State Electricity Distribution Company Limited) has taken electricity supply from three grids. It is called Receiving Sub Station (RSS). The power supply is taken from the Chinchwad grid for receiving substation at Pimpri-Chinchwad station, the Ganeshkhind grid for Range hill receiving substation, and the Parvati grid for Vanaz receiving substation. For this, 5 to 6 km long 133 kV power cables have been laid using the latest technology. Due to this, in case of any technical failure in one grid, it will be possible to continue the metro service by providing electricity from the other grid. The receiving substation at Range Hill has been built with the capacity to supply electricity to both corridors of the metro simultaneously.

Four transformers have been installed in each receiving substation and the 132 kV power supply has been stepped down to 25 kV, 25 kV, 33 kV, and 33 kV. 25 kV power supply is used for traction and its feed is released in train Overhead Electric Wires (OHE). The 33 kV power supply has been given to all metro stations. For this, electric cables of 33 kV capacity have been laid along the entire 33.2 km route. An Auxiliary Sub Station (ASS) is constructed at each station. This power is supplied to elevators, escalators, air conditioning (AC), and electrical systems in the station through the auxiliary substation.

Pune Metro has planned to generate solar power on a large scale. Solar power generation sets have been installed on the roofs of each station and on the roofs of buildings. Through this, it will be possible to generate 11 megawatts of solar power. Integration of solar-generated energy with the power supply system is done. This will save a lot of energy.

A SCADA system has been installed to control all receiving substations (RSS), auxiliary substations (ASS), and OHEs. The entire traction and power supply system can be controlled through this SCADA system. The main computer of the SCADA system is installed at OCC at Range Hill. Complete traction and power supply information is available online on the display at OCC. So it is easy to control.

On this occasion, the Managing Director of Maha Metro, Dr. Brijesh Dixit said, “World-class traction and power supply systems have been installed for Pune Metro. Therefore, it is planned that Pune Metro will continue to get uninterrupted power supply.”

KOLKATA (Metro Rail News): The Kolkata Metro Rail Corporation (KMRC), the implementing agency of East-West Metro, has started fixing steel props to avoid further deterioration of the crack-ridden buildings in Bowbazar’s Madan Dutta Lane, officials of the agency said.

The agency is also grouting its foundation, in an effort to prevent future tilt because of subsidence.

However, a number of the engineers working on the East-West Metro project and other Metro tunnelling projects have stated that such precautions should have been taken before beginning to build the “cross passageways” that connect the two tunnels.

In order to pump concrete mix under the foundations of certain houses that were cracked first shown on the 14th of October morning due to subsidence caused by Metro work, pumps with lengthy hose pipes were set up on the 17th of October in the narrow road.

Senior officials stated that the foundation’s grouted concrete mix would fill in any gaps beneath the structures and stop the soil beneath them from sliding further. This will guarantee that the structures don’t get any additional cracks.

“We want to repair some of the buildings in Madan Dutta Lane where minor cracks have appeared and ensure the residents return home at the earliest,” said N.C. Karmali, director, projects, KMRC.

“A team of consultants has already assessed the condition of the affected buildings. After repairs, we plan to invite them to revisit the buildings and identify those where residents can return.”

“Since two similar disasters had taken place in the area since 2019, the authorities should have taken additional precautions. They should have fixed props for the old buildings before starting work on cross passages,” said an engineer involved in the project on another stretch.

A team of experts from Stup, a consulting agency, has assessed over 10 buildings where cracks appeared on Friday, said a KMRC official. “There was no deliberate delay after the cave-in.”

The KMRC has said it would pay Rs 5 lakh each to the house owners who cannot return home within 30 days from Friday. The affected shop owners whose establishments measure less than 100sq ft will receive Rs 1.5 lakh as compensation. The ones with establishments measuring above 100sq ft are entitled to Rs 5 lakh as compensation.

“Work inside the Metro tunnel cannot be put on hold for long. We want to start it as soon as the shifting of loose soil stops and the area has completely stabilised,” said a KMRC official.

Shri Ashwini Vaishnaw inaugurates India’s First Aluminum Freight Rake - 61 BOBRNALHSM1 at Bhubaneswar Railway Station

BHUBANESWAR (Metro Rail News): Union Minister for Railways, Communications and Electronics & Information Technology, Shri Ashwini Vaishnaw inaugurated India’s First Aluminum Freight Rake – 61 BOBRNALHSM1 at Bhubaneswar Railway Station on 16th October. The rake’s destination is Bilaspur.

This is a dedicated effort for Make in India program as it has been fully designed and developed indigenously in collaboration with RDSO, HINDALCO and Besco Wagon.

Features of Aluminium Rake:

Fully Lockbolted construction with no welding on superstructure.
The tare is 3.25 tons lower than normal steel rakes, 180 ton extra carrying capacity resulting in higher throughput per wagon.
Higher payload to tare ratio 2.85.
The reduced tare will reduce carbon footprint as lower consumption of fuel in empty direction and more transport of freight in loaded condition. A single rake can save over 14,500 tonnes of CO2 over its lifetime.
80% is resale value of the rakes.
Cost is 35% higher as the superstructure is all aluminium.
Lower maintenance cost due to higher corrosion and abrasion resistance.
Iron industry consumes a lot of Nickel and Cadmium which comes from import. So, proliferation of Aluminum wagons will result in less import. At the same time, this is good for local aluminum industry.

GDA plans two new metro routes in Ghaziabad

Staff Reporter

17/10/2022

GHAZIABAD (Metro Rail News): The Ghaziabad Development Authority (GDA), plans to create a detailed project report (DPR) in order to connect Noida Sector 62 Metro Station with Sahibabad and Mohan Nagar Metro Station with Vaishali through Metro Lite, in the city of Ghaziabad, Uttar Pradesh which is likely to get two new metro routes.

Metro Lite is an urban transit system that acts as a feeder system for the city’s current metro systems with lower projected ridership.

The Delhi Metro Rail Corporation (DMRC) submitted the GDA with a project report in January 2020 that included an estimated expenditure for both routes. For the Sector 62 and Sahibabad route, it estimated a budget of Rs. 1,517 crores, while for the Vaishali and Mohan Nagar route, it estimated a budget of Rs. 1,808.22 crores.

The GDA also received a DPR in 2021 for a ropeway project with a projected 80,000 weekly ridership.
Due to funding concerns with the authority, both the ropeway and Metro Neo projects were dropped, which has hampered the development of a multimodal transportation system.

“We will now prepare a DPR for the two routes with the Delhi Metro Rail Corporation (DMRC). The official communication will be sent to DMRC this week. They will find it easy to prepare the DPR as they have already conducted detailed studies for the two routes,” Rakesh Kumar Gupta, chief engineer, GDA told the newspaper Hindustan Times.

“Once the DPR is prepared, we will send it to the state government for approval and also seek funding. The per kilometer cost of Metro Lite is about Rs. 150 crores, lower in comparison to Metro. The passengers per hour per direction (PHPDT) of Metro Neo is about 8,000 and about 15,000 for Metro Lite. Hence, we are now looking to prepare a DPR for Metro Lite. The ropeway project is not being considered at present,” he added.

The residents and everyday commuters between Ghaziabad, Delhi, and Noida have made the connection of the relevant metro routes a top priority.

“The authority has no funds and the two metro routes cannot be connected with any other mode of transport. The GDA must try to get their pending infrastructure development funds from the state government and execute the project,” Rajendra Tyagi, councilor, Raj Nagar, told Hindustan Times.

“The GDA is just trying to confuse people by jumping from one project to other. They must wait till their financial position improves and build metro connectivity so that commuters don’t need to break their journey midway,” said Sanjay Singh, councilor, Shipra Sun City, Indirapuram.
