Mexico City rail overpass collapses onto road

MEXICO CITY (Metro Rail News): President Andres Manuel Lopez Obrador vowed a comprehensive and open inquiry into the cause of the crash when cranes were pulling two train cars that were left dangling from a light-rail overpass that collapsed on May 3.

On Monday night, a concrete slab supporting a metro track in Mexico City gave way in a horrifying roar, sending two rail cars plunging into a highway below. Twenty-four people were killed. It was the latest in a string of misfortunes for a grid that serves as the bedrock of the capital’s transit network, with millions of impoverished and working-class people depending on it.

On Tuesday, the fatal collapse of a subway overpass in Mexico City sparked grief and political recriminations, throwing senior politicians on the defensive as they answered concerns about shoddy work and inadequate upkeep for one of the world’s busiest subway networks. Authorities suspended recovery operations soon after they started, citing the danger of further train parts and rubble crashing down into the route

Claudia Sheinbaum (Head of Government of Mexico City) said that police were trying to locate the deceased, which included teenagers. One individual was saved alive and taken to the hospital after being stuck in their vehicle under the rubble. Seven of the people who were taken to the hospital were in “grave condition” and were having surgery, according to police. When Foreign Minister Marcelo Ebrard was mayor of Mexico City, the Metro 12 line that passes over the collapsed overpass was designed almost a decade ago.

“The Metro disaster that occurred is a horrific catastrophe. My heart goes out to the victims and their families “On Twitter, Ebrard wrote.”Of course, the reasons must be investigated, and roles must be assigned.” Many political analysts see Ebrard and Sheinbaum as the most possible successors to President Andres Manuel Lopez Obrador when his six-year term ends in 2024.

Alstom delivers the 100th electric locomotive of 12,000 HP to Indian Railways

locomotives/Representational Image

Alstom, India’s biggest multinational sustainable mobility provider with a comprehensive portfolio of offerings, has successfully manufactured and delivered the 100th electric locomotive to Indian Railways. As part of the contract worth €3.5 billion won in 2015, the company will be supplying 800 fully electric high-powered double-section locomotives of 12,000 HP (9 MW) for freight service, capable of hauling ~6,000 tonnes at a top speed of 120 km/hr. This is the largest Foreign Direct Investment project in the Indian Railway sector.

In the financial year 2020-2021, Indian Railways recorded a freight loading of 1,232 million tonnes, which was 2% higher than the previous fiscal. Introduction of faster trains has helped increase the average speed of transportation by 83% leading to a shorter turnaround time and has supported the movement of essential goods during COVID-19 times **.

With the first Prima T8TM WAG-12Binducted for commercial service in May 2020, these locomotives are transforming the heavy freight transportation landscape of India. Deployed for operations on major freight routes, including Dedicated Freight Corridors, the Prima T8TM WAG-12Be-Locos have already clocked over close to 5 million kilometres hauling a wide range of commodities. These locomotives also made the inaugural run on the first fully operational sections of the Dedicated Freight Corridors, in December 2020. Some of the key commodities moved by these e-Locos include – coal, cement, food grains, fertilisers, petrochemical products, minerals, and posts/ parcels, across 17 States & 2 Union Territories.

Speaking on this milestone, Alain Spohr, Managing Director – Alstom Indiasaid, “I’m pleased to mention that despite challenges posed by COVID-19, we have been able to successfully manufacture and deliver 100 e-Locos to the Indian Railways in less than a year. Due to the intricacy of the project, it is really an honour to work on a first-of-its-kind ‘Make in India’ project that resulted in a technology breakthrough for the nation. Our successful collaboration with Indian Railways is paving the way for bringing advanced innovation and technology to the Country. Alstom is committed to delivering safe, reliable, and efficient solutions for IR’s revolutionary journey towards becoming the world’s first 100% green railways”.

The Prima T8TM WAG-12Be-Locos are built at one of India’s largest integrated greenfield manufacturing facilities at Madhepura (Bihar). Spread across 250 acres, this industrial site is built to international standards of safety and quality. The site has installed production capacity of 120 locomotives per annum and Alstom has progressively achieved over 85% indigenization. With these powerful e-Locos being manufactured within the country, India has become the 6th in the world to join the club of countries producing high horsepower locomotives indigenously.

The project also includes setting up of two ultramodern maintenance depots in Saharanpur (Uttar Pradesh) and Nagpur (Maharashtra). These depots are equipped with the latest technologies and features to anticipate breakdowns thereby enabling proactive maintenance of India’s most advanced freight locomotives at significantly lower costs. The depot in Saharanpur is currently operational and houses a ‘Training Centre’ equipped with a loco simulator and smart classrooms for skill development of railway employees and loco pilots. Till date, more than 500 loco pilots from Indian Railways have been trained and going forward, an additional 500 will be trained annually. The Nagpur depot will be functional next year.
