Southern Railway inducts WAP-7 fast locomotive

The Southern Railway on Wednesday inducted into its fleet the first WAP-7 broad gauge electric locomotive. Built by the Chittaranjan Locomotive Works, the advanced 6000 Horse power locomotive has a potential to conserve energy.

According to railway sources, the salient feature of the WAP-7 locomotive is its capacity to regenerate energy lost while braking.

When deployed on down gradient sections, the locomotive would conserve energy to the tune of 30-35 per cent.

In-built system

It has an inbuilt microprocessor-based fault diagnostic system for easy trouble shooting.

With a maximum speed of 160 kmph, the locomotive has an acceleration capacity to attain 110 kmph in six minutes while hauling a 24-coach train.

“We are already operating WAP-7 locomotives drawn from Secunderabad in the Chennai-Bangalore stretch. Southern Railway is likely to get a few locomotives of this class and the first one rolled out on Wednesday.

It is faster compared to the conventional electric locomotives,” a senior railway official said.

New energy-efficient loco introduced for high speed trains

The Nagpur division of Central Railway has introduced a new electric locomotive ‘WAP 7’, a high speed engine indigenously developed by Chittaranjan Locomotive Works, which is capable of hauling trains at speeds ranging between 140-160 km per hour. The Nagpur division authorities were making efforts since last four months to get the new locomotive and their efforts bore fruit with Railway Board alloting one WAP7 loco being used in Hyderabad-Nizamuddin Dakshin Express from February 2, a release from Nagpur division of Central Railway said today. The Sampark Kranti Express is also expected to get WAP 7 in next one month. The Nagpur division also planning to switch over to WAP 7 locos in Indore Trishatabdi Express and Nagpur-Indore weekly Express. The requirement of banker engine in ghat section between Nagpur and Itarsi is eliminated, resulting in saving of 10 minutes time as well as saving electrical energy about 700 units per train while descending the ghat. It will also save the banker engine use and energy. Due to high acceleration the punctuality is maintained in division. With a maximum speed rating of 180 km/h, the WAP-7 boasts of the most phenomenal acceleration figures while hauling mail/express trains. The WAP-7 can also haul loads of 24-26 passenger coaches at a speed of 110 plus km per hour. It is also known to haul 16 heavyweight Air Conditioned coaches. At a trial conducted by Indian Railways, it clocked a speed of 177 km/h. It is the most successful passenger locomotive in the Indian Railways portfolio after the WAP-4. It is used to haul premium trains like the Rajdhani Express and the Shatabdi Express apart from other regular mail/express trains. As of now, 300 WAG 9, WAP 7 and WAP 5 locos running on the network annually save about 100 million units of energy, saving 105 tonnes of CO2 per annum, the release added.…ns/961069.html

SAIL to set up railway wagon factory

Steel Authority of India Ltd (SAIL) is currently in talks with RITES Ltd, a subsidiary of Indian Railways, for jointly setting up a railway wagon making factory in West Bengal.

For the project, SAIL is expected to provide its surplus land in Kulti near Burnpur, West Bengal. The location of the plant could be near Chittaranjan Locomotive Works.

The SAIL Chairman, Mr C.S. Verma, said the factory is expected to produce 1,200 railway wagons a year. “At present, we are engaged in coming up with a feasibility study for the project. Details of the venture including the investment required, equity shareholding pattern and other such points have not been decided yet,” he said.

Earlier this month, the Railway Minister, Ms Mamata Banerjee, had said that the tentative name of the factory would be Bengal Wagon Industry. “This will be the third wagon manufacturing plant in West Bengal after Braithwate and Burn Standard,” Ms Banerjee had said at that time.

The proposed joint venture with RITES would be a first foray into manufacturing for SAIL. The company already has a monopoly in supplying rails and analysts say that a venture into manufacturing would further strengthen the company’s presence in the railway equipment market. The joint venture company would face competition from Titagarh Wagons and Texmaco Industries for supplying wagons to the Indian Railway.

At present, the demand for wagons in the country is around 25,000. With numerous dedicated freight corridors coming up, this number is set to increase in the near future.
