New Delhi (Agencies): A re-examination will be conducted by the Railway Recruitment Board (RRB) on Sunday for the post of assistant loco pilots after the exams were cancelled last year .  

The exam will be conducted for about 2000 posts of assistant loco pilots under a new system.

The exams were cancelled in June last year after the question papers were leaked. The leakage case is being investigated by the CBI.

The fresh examinations will be held in Mumbai, Nagpur, Solapur and Ajmer.

Since the question paper leakage episode, railways have altered the examination system to avert such leakage.

 "We are now following a secret procedure with checks and balances in preparing the multiple question sets in the new system," said a senior Railway Ministry official.

In contrast withthe earlier practice, there is no dependence on any individual in the new system.

 "Earlier it was RRB centric. Now with the involvement of zonal railways and divisions, RRB team has now less opportunity in interfering with the system," said the official.

Since the new system has been introduced, RRB has conducted exams for about 36,000 vacant posts in safety categories in December 2010 and January this year under the new system.
