Union minister Nityanand Rai launched a website and a mobile application on Thursday to facilitate the railway police in addressing complaints of passengers from across India and crime detection by integrating the criminal database online.

Railway Minister Piyush Goyal on Monday said Congress president Sonia Gandhi's concerns over the corporatisation of the Modern Coach Factory in Rae Bareilly were based on "misguided, imaginary fears" and urged her not to fall for "fear-mongering" on loss of jobs.

This was the highest single day fatalities recorded on the suburban rail network, often called Mumbai's lifeline, in recent times, they said.

Railway traffic in the hilly section of the Central Railway has been affected as one trolley of the second coach of the Gorakhpur Antyodaya Express derailed in Maharashtra early on Thursday, an official said.

A power car needs 40 litres of diesel per hour per non-AC coach while an AC coach needs 65-70 litres of diesel per hour. Around three units of electricity is provided by one litre of diesel, so a non-AC coach uses around 120 units of electricity per hour.

Soon after the Congress leader raised the issue during the Zero Hour, the Railways rejected her charge and said the factory will remain under government control.
