26 Oct :In a bid to reduce its expenditure on diesel, Indian Railways has decided to develop dual fuel engines which would also use CNG as Railways spend about Rs 8,000 crore a year on diesel.
"We have decided to use CNG in train operations with the aim of optimising the substitution of diesel and accordingly a project is being launched," said a senior Rail Ministry official.
Under the project, 50 diesel multiple units (DMUs), also known as diesel power cars, will be converted into dual fuel engine with capability of running on CNG.
"This means 50 converted DMUs will be running on diesel as well as CNG in the first phase," said the official.
Indian Railways Organisation for Alternative Fuel, which is coordinating the project, has invited tenders for conversion of DMUs to dual fuel engine with CNG capability.
Since CNG is available only at a few places, the dual fuel engine will be utilised only on certain identified routes, said the official."Since CNG is cheaper, we expect to cut down fuel cost with the introduction of CNG-based engine," said the official.
Besides cost reduction, utilisation of CNG, a clean fuel, will also help in improving the environment.
