He further added that during the same period, the entire train network will be equipped with bio-toilets and that the ambitious projects being implemented to make the railways a major engine of the country's growth. He also informed about a proposal to lay separate rail lines for freight trains and there is also a plan to lay at least 10 km track per day. Insisting that passenger safety is a major priority for which the latest technology is being introduced and the government was working on removing all un-manned level crossings across the country.
