Indian Railways conducted a test run of the 3.5-km-long freight train, Super Vasuki, with 295 loaded wagons carrying over 27,000 tonnes of coal between Korba in Chhattisgarh and Rajnandgao in Nagpur on August 15 as a part of the Azadi Ka Amrit Mahotsav celebrations. The trial run by the South East Central Railway left Korba at 13:50 and took 11.20 hours to cover the distance of 267 km. 

This was the longest and heaviest freight train ever run by Indian Railways, the national transporter said, adding that the train took about four minutes to cross a station. 

The amount of coal carried by Super Vasuki was enough to fire 3,000 mw of power plant for one full day, officials said. This was three times the capacity of existing railway rakes (90 cars with 100 tonnes in each), which carry about 9,000 tonnes of coal in one journey. 

The train was formed by amalgamating five rakes of goods trains as one unit. 

Indian Railways planned to use this arrangement (longer freight trains) more frequently, especially to transport coal in peak demand season to prevent fuel shortages of power stations, the officials said.
Earlier this year, coal shortages had pushed the country into a severe power crisis.
