The Ministry of Railways has expressed serious concern over the “uncontrolled” excess in estimates and spending of funds much beyond the sanctioned limit in the new line, gauge conversion and gauge doubling works in the country.Identifying specific areas of “extravagant” and “lavish” spending, the Ministry has written to the Chief Administrative Officers (Construction) of all zonal railways,pointing out that loans were being taken for executing projects for which interest had to be paid, and therefore any change in the detailed estimate for the proposed projects should be“summarily rejected”.The Railways spends thousands of crores of rupees every year for executing projects of new lines,gauge conversion and broad gauge doubling. The finding of the Railway Board is that revised estimates are submitted after expenses beyond the sanctioned limit are incurred.Though repeated instructions were given to the Chief Administrative Officers that revised estimates should be submitted in time for approval by the competent authority and no contractual liabilities should be entered into till then, there were violations, leading to the “uncontrolled excess in the estimates over the sanctioned qualities”.Some of the deviations identified by the Railway Board were raising of the embankment while laying track to accommodate limited height subway/road under bridge, causing large variation in the cost of land acquisition as well as earth work. Track centre, the spacing between tracks in doubling projects, were more than what was prescribed, resulting in more land acquisition and cost.In the new line, gauge conversion and double line projects, passenger amenities like high level platform were provided in excess of what was mandated in the detailed estimate.During scrutiny, it was observed that in a 29km gauge doubling work, more loop lines than were required were laid without the train traffic in the section being taken into account.
