Diesel locomotive to come with fuel saving device

Indian Railways has decided to install a new fuel saving device in diesel locomotives which will result in saving over Rs. 60 crore annually, an official said Thursday.

To begin with, the auxiliary power unit (APU) has been installed in 12 existing diesel locomotives through retrofitment.

“In future, Indian Railways plan to fit APU in all newly built diesel locomotives which will then result in saving of more than Rs. 60 crore annually,” the official said.

“Use of the device also results in reducing carbon emission by the train engine,” he added.

High HP dual cabin diesel locomotive introduced

A newly manufactured high horsepower diesel locomotive with dual cabin arrangement has been introduced by the Railways for the first time in south India.

The 4,500 horsepower loco commissioned this month would be homed at the Diesel Loco Shed in Tiruchi, the biggest shed in Southern Railway zone with a holding of over 150 diesel engines including 27 EMD-type locos. This will be the first shed in south India to home the dual cab loco.

The loco pilot cabin has been provided in both ends of the diesel engine similar to that of an electric locomotive. It could be operated from front and rear cabin.

At present, all diesel engines being operated in south India are provided with only single cabin.

The dual cab loco would provide accurate visibility to the loco pilots to sight the signals and any obstructions on the track even at a speed of 130 kilometre per hour.

Dispatched from the Diesel Locomotive Works, Varanasi, the dual cab loco is presently being used for training loco pilots of Salem and Palakkad railway divisions on handling the engines.

The loco would be extensively used for hauling prestigious super fast trains such as the Rajdhani and the Jan Shatabdi expresses of south India.

Another unique feature of the dual cab engine is that it has been provided with a parallel display system for the Assistant Loco Pilot to monitor the performance of the engine from his seat. This facility is not available in other locomotives, railway officials here told ‘The Hindu’.

Equipped with computer controlled braking system, the engine can run at a maximum permissible speed of 130 kilometres per hour.

The seats inside the cabin have been ergonomically designed and various parameters such as speed, air pressure in brake pipes, feed pipes, main reservoir tanks have been customised and displayed in a computer (LED) display, eliminating the conventional gauges.

The control panel has been fabricated with fibre reinforced plastic material to give an elegant look.

With a 5,000-litre fuel tank capacity, the engine with six traction motors weighs 123 tonnes.

It would be utilised for hauling Rajdhani and Jan Shatabdi trains upon getting a clearance from the Commissioner of Railway Safety, the officials said.


Rs 200-cr locomotive plant to be set up in Sehore

An Indo-US joint venture firm has announced to set up the first diesel locomotive plant to manufacture environment-friendly and fuel-efficient railway engines at Sherpur village in the adjoining district of Sehore.

The firm will invest over Rs 200 crore for the project. Disclosing it to the media persons the Managing Director of the Daulatram Engineering Services Pvt Ltd CP Sharma said his firm had entered into a partnership with the US-based National Railway Equipment Company (NREC) to star the pioneer project in the state.

According to him, it was the first such example in which a private firm was given the permission in the county to manufacture diesel locomotive.

Madhya Pradesh Chief Minister Shivraj Singh Chouhan and Industries Minister Kailash Vijawrgiya will lay the foundation stone for the ambitious project at Sherpur village on Saturday, Sharma said.

The plant will be set up in a 50 acre land already acquired by the company. “The joint venture has already bagged the order from Indian Railways and Chennai Metro to manufacture two such engines for them. These are currently being manufactured jointly by the company along with Diesel Locomotive Modernisation Works in Patiala,” he said. These two locomotives will be rolled by January next from the Patiala unit, Sharma said.

The next five locomotives will be rolled out from the new facility in next 18 months.


Indian Railways to get its most powerful diesel locomotive

Locomotive major Electro-Motive Diesel Monday said it has completed the design for a high-horsepower locomotive for the Indian Railways.

According to the company, the new design – WDG5 – would be developed into the most powerful diesel locomotive in the country with a power output of 5,500 bhp.

“This diesel locomotive has an output of 5,500 bhp, which will make it the strongest diesel locomotive ever to run on the Indian rail network,” the company said in a statement.

The company further said that the locomotive has a tractive effort of 560 kn and can pull more load at higher speeds with less emissions than engines which are currently in use.

“We have great confidence that the WDG5 will be the locomotive of tomorrow for Indian Railways,” said Glen Lehmann, chief marketing officer, international, Electro-Motive Diesel.

The design entails the usage of modern technologies like electronic fuel injection and more.

“It includes electronic fuel injection, radial grids and high adhesion, lightweight fabricated bogies,” Lehman said.

The interiors of the locomotive would have crew-friendly features and modern controls.

“It has modern driver interface and crew-friendly features, such as an air conditioned cab and toilet, which is another first for the Indian Railways’ fleet.”

The new design was completed in collaboration with the Research Designs and Standards Organisation (RDSO) and Diesel Locomotive Works (DLW) of the Indian railways.

Currently, the company provides service support to Indian railways’ locomotive facilities at multiple locations.
