Hyderabad: In the recent past we have seen a series of accidents across the country.authorities are now checking the possibility of Saturday's Hirakhand Express train mishap which was the fifth accident in the last six months.Weeks ago, a goods train derailed at Wihirgaon station on Kazipet-Balharshah section of South Central Railway, leading to a major disruption of train movement on the important "trunk route".The number of vacancies for safety officers shows a clear case of neglegence.In the East Coast Railway sector, where the accident occurred, there is a 24% vacancy in safety official roles, as per records of East Coast Railway.Meanwhile,1.42 lakh posts for safety staff remain vaccant across India, which, experts say, is a major concern and clear case of official apathy."The pressure on crucial safety staff has remained very high over the years and this has also been pointed out in various internal reports over the years. Not only are there huge vacancies but the existing staff work under sub-standard conditions.While higher-ups in the ministry might be awaiting the assistance of technology before filling vacant posts, the automated anti-collision device tested previously does not seem very promising. The posts need to be filled up immediately," pointed out a retired senior official from SCR.There are only 4,827 posts filled out of 6,398 Sanctioned strength of the engineering staff,remaining 1,571 are vacant in the East Coast Railway.In the same manner 67 posts in security,93 in signal and telecom,and 613 in electrical local running are vacant as per details from the Railway Board."With such high vacancies in critical posts,mishaps are bound to happen.
