Bengaluru :
The Rail Wheel Factory (RWF) in Yelahanka has been given the green signal to supply wheels to Kolkata Metro Rail Corporation. This marks the first time any Metro Rail in the country has opted for cast wheels for coaches, opening up a whole new market for the factory.
The clearance was given on Monday by the Research Design and Standards Organisation, Lucknow, an organisation under the Ministry of Railways, Rajeev Gupta, General Manager of RWF, told Express.
“We will be providing wheel sets (wheels and axles) for the coaches of the Kolkata Metro, which are being readied at the Integral Coach Factory in Chennai. They will initially be supplied for the trial runs of three coaches of a Metro train, which would be 24-wheel sets,” the GM said.
This followed three months of negotiations and paper work between the Kolkata Metro and RWF. The trial runs could take place over a year since it is a whole new experiment being undertaken of using cast iron wheels for Metro coaches. “When it is successful, we will be permitted to supply wheels. We could bag an order to supply between 500 and 1000 wheels,” Gupta said.
When asked about the chances of it passing the trial runs, he said, “We will sail through it. We have successfully conducted the Finite Element Analysis test, which is a simulation test done emulating a train running at high speed.” The fastest Metro trains run at a speed ranging between 60 to 70 kmph. “Our wheels run at 110kmph regularly and all Rajdhani trains have them. They can touch up to 130 kmph,” Gupta said.
RWF, the country’s largest manufacturer of wheels sets, had approached Delhi Metro Rail Corporation and Bangalore Metro Rail Corporation in connection with the supply of wheels. “However, since Metro trains only use forged iron wheels which are imported, RWF was not able to convince them to make it a wheel-supplier.” It has the capacity to manufacture nearly 2 lakh wheels and 72,000 axles by casting technology.
