GE Transportation rolled out Indian Railways’ first Evolution Series locomotive from the paint stall, revealing the railroad's new paint scheme. The ES43ACmi (Indian Railways’ class - WDG4G) locomotive, painted in a distinctive red and yellow pattern, is the first of 1,000 diesel freight locomotives that GE Transportation will deliver to Indian Railways as part of a $2.5 billion order. The bright colors hold special meaning in India with red representing energy and yellow representing freshness.

“It is great to see Indian Railways’ first locomotive emblazoned in the railroad’s ornate paint scheme,” said Nalin Jain, President and CEO of Asia Pacific for GE Transportation. “This is a great example of the “Make in India” initiative, which will instill a sense of pride in Indians nationwide as it hauls freight throughout the country.”

The locomotive donned its new coat of paint following nearly two months of test and validation. Indian Railways’ new color scheme was completed using approximately 50 gallons of paint. The coating and paint will provide the locomotive protection in the harsh environments where Indian Railways operates.

With paint completed, GE Transportation is preparing to ship the locomotive in a few weeks. It is expected to arrive in India later this year.

The first of 1 000 Evolution Series diesel locomotives which GE Transportation is to supply to Indian Railways over 10 years was unveiled at the manufacturer’s plant at Erie in the USA on June 1.

“This new ES43ACmi locomotive is the ideal solution for Indian Railways’ modernization efforts,” said Yuvbir Singh, Vice President of Global Locomotive Operations for GE Transportation. “The design is based on our Evolution Series locomotives. It will provide greatly improved fuel efficiency and emissions compared to Indian Railways’ existing non-Evolution Series fleet.”

The ES43ACmi locomotive is one of two models GE Transportation is building for Indian Railways as part of the order. It’s a dual-cab locomotive with a 4,500-horsepower engine. The second locomotive, model ES57ACi, features a 6,000-horsepower engine. It is currently in the design phase and will begin production later this year.

These new locomotives are part of the Government of India’s Public Private Partnership program to modernize the country’s rail infrastructure.

GE Transportation is to supply 700 locos of 4 500 hp and 300 of 6 000 hp under a US$2·6bn joint venture agreement signed with the Ministry of Railways in November 2015, the largest contract ever won by GE in India. They will have Tier 1 GEVO engines.

The first 100 of the twin-cab 1 676 mm gauge locos locomotives are to be exported from the USA complete or in kit form. To meet the requirement for local production under the government’s Make in India programme, the other 900 are to produced with mainly Indian components at a factory which GE is building at Marhowra in Bihar. This is expected to be completed later this year, and will produce two locomotives per week for the current contract.

GE will also develop facilities at Roza in Uttar Pradesh and Gandhidham in Gujarat to support long-term maintenance of the fleet.

The 1st of the emission-compliant diesel-electric locomotives has arrived at Mundra Port. Marking an important step in rail modernization.

A remarkable milestone reached today handing over the first two Evolution Series locomotives to Indian Railways and the unveiling of the Roza maintenance shed – a state-of-the-art monitoring, maintenance & training facility in the Shahjahanpur district of Uttar Pradesh.

Brain Behind GE Locomotives is an Indian from the state of Kerala.

It’s the technology, not the achievement, that really excites Kumar, a consulting engineer with GE Transportation Systems who holds more patents than any other GE employee. “I’ve worked on every new product transportation has come up with from the conceptual stage to prototype and first production,” says Kumar, 65. “I really enjoy solving problems in a slightly different way.”

Indian Railways operationalizes India’s most powerful diesel-electric locomotive, the 6000 HP “ ANGAD ” manufactured by GEDLPL at its modern locomotive manufacturing plant in Marhowra, Bihar as part of ‘Make in India’ Program .

Indian Railway’s first 6000 HP diesel-electric locomotive started its inaugural run in the service over Northern Railway in June 2020 and the locomotives are currently in operation over North Eastern Railway and Northern Railway. The heavy haulage capabilities of Indian Railways will get a big boost with the start of operation of “ANGAD”.

The introduction into service of “ANGAD” 6000HP locomotives marks another significant milestone for GE Transportation a Wabtec Company in the execution of Marhowra Locomotive Project having already supplied 200+ locomotives to Indian Railways.

The 1st 4500 HP locomotive entered revenue service in October 2018. A shining example of cross functional team effort, building local capabilities, seamless execution in strong collaboration with Indian Railways & Govt of Bihar.

Alstom Locomotives in India

Indian Railways set to get 1st high-speed electric locomotive in March

India’s dream for high horse power locomotive moved closer to reality with the arrival of the first bodyshell of 12000 HP loco from Alstom France at Kolkata port on Wednesday.

This first-of-its-kind high-power electric locomotive will be used to haul freight trains at twice the existing speed by next year.

The bodyshell for the fleet of the twin-section electric locomotives which Alstom is to supply to Indian Railways was unloaded at Haldia, ready for delivery to the factory at Madhepura where it will be assembled.

In November 2015, the public transporter inked a contract with the French company to manufacture 800 such train engines over the next 11 years in a joint venture at the Madhepura locomotive factory in Bihar.

This is the first major FDI (Foreign Direct Investment) project in the rail sector.

The first such locomotive, estimated to cost about Rs 30 crore, will be assembled with components brought in from Alstom’s factories in France and will have its trial run by February next year.

The contract allows for the first five locomotives to be imported, but the remaining 795 are to be manufactured locally in support of the government’s Make in India campaign.

The total contract is worth above three billion euro. This project includes the set-up of a plant at Madhepura (Bihar state) and two maintenance depots at Saharanpur (Uttar Pradesh state)and Nagpur (Maharashtra state). The delivery of the locomotives will spread between 2018 and 2028.

The locomotive will run at a speed up to 120 km/h.

More than 1000 workers engaged at site, over a period of 12 months, to enable commencement of production at Alstom’s first e-loco facility in India. Alstom presents a riveting story of the challenging journey, which can be viewed here:

The Railways is currently using 6,000HP locomotives for freight services.

PROJECT GP 140

The increase in speed would also result in improving line capacity in the rail network, a railway official said.

As per schedule, 35 locomotives would be rolled out from the factory by 2020, 60 in 2021, followed by 100 every year till the target of 800 is completed.

Alstom today (12-10-2017) successfully commenced production at its greenfield electric locomotive manufacturing facility in India. Located at Madhepura, in the state of Bihar, it is Alstom’s first electric locomotive manufacturing facility in the country, set to transform the heavy freight transport landscape in the country.

Commencing production on schedule, the construction of the plant is a remarkable achievement in the construction of greenfield facilities in the country. The Prima T8 (WAG12) locomotive, which will be produced in this new factory, is part of Alstom’s Prima range of locomotives and has been specially adapted for Indian network. The first two car body shells have already arrived at Madhepura and will be soon fitted and assembled at the plant. The first locomotive will be ready for roll-out early next year. The first 5 locomotives by 2019 followed by 35 locomotives by 2020, 60 in 2021, and by 100 every year till the target of 800 is completed.

A true embodiment of government’s ‘Make in India’ vision and built to the highest standards of quality and safety, this facility is part of a joint venture between Alstom (74%) and Indian Railways (26%). Spread across 250 acres, it currently employs 70 people, with plans to ramp it up at a rate of 25% every year till it reaches full capacity. The facility also aims to employ local youth, basis the required skill sets, to support socio-economic development of Madhepura.

WAG 12 UPDATES AS ON 20-05-2020.

WAG-12 has two variants.

The first model was the WAG-12A, of which only one unit has been manufactured. This design experienced issues with ride quality, which resulted in major modifications to the suspension and the bogies.

The final design, now known as WAG-12B, has been approved by the Indian Railways.

New Features on the WAG-12

· Two units (A and B) permanently coupled to each other. Both units only have cabs on the outward-facing ends.

· Both units will be controlled from the working cab.

· While both units will be provided with one pantograph each. However, only one pantograph will be raised at a time and will feed power to both the units through a high-tension overhead link.

· Both units have been provided with a toilet for the crew.

· The units are connected to each other through a vestibule and gangway.

· A major departure from existing designs of locomotives is that high voltage apparatus like the vacuum circuit breaker is now inside the body of the locomotive in a special cubicle. The roof of the locomotive is almost empty except for the pantograph.

· This locomotive has a larger wheel diameter, compared to other freight locomotives in service on the IR.

· This locomotive also features the much-awaited ‘Brake Blending’ facility. If regenerative braking (AKA electric or Electro-Dynamic brake) is applied and found insufficient, a proportionate quantum of the pneumatic brake is applied simultaneously by the locomotive.

· To improve reliability, almost all hardware switches and controls are replicated on the DDU (Driver Display Unit). Thus, several functions can also be controlled using ‘Soft Keys’.

· A dehumidifier for air intake ensures that only dry air is used for cooling and ventilation systems. This will improve equipment life and insulation.

· An automatic flap system regulates the entry of air into the locomotive’s ventilation system and ensures uniform flow in various conditions.

· Tube drive equipped with self-aligning roller bearings for better suspension.
