A detailed project report (DPR) for all these projects with proper due diligence has to be prepared.
In addition, the concerned zones also have to estimate the actual cost and the rate of return of these lines without being guided by budget estimates outlined in the pink book.
These projects will then be put up for approval from the Rail Ministry, Finance Ministry and the Union Cabinet.
