Due to the slow running of trains, four passenger trains face the problem of running down of batteries.

Power equipment major BHEL has said that it has bagged an order from Indian Railways for installing 2 MW rooftop solar photovoltaic systems at Diesel Locomotive Modernisation Works (DMW) in Patiala. The contract agreement was signed between BHEL and the Indian Railways Organisation for Alternate Fuels (IROAF).
