* More the number of RMs, more will be their pet (loss making) trains and projects. Not all RMs are hard working and contribute to IR like Mr Prabhu does, n are a burden on the IR officials who often put their demands most of which are not in the interest of IR.
* Monitoring safety is a function of Rly employees and officials, not RMs, else there should be 17 RMs one for each zones and a few more to oversee the railway production units.
* Qualification of a Minister is...
more... the victory of an election or nomination to the house, which is no qualification to understand and govern/manage/administer the mammoth organisation called IR. More over, MR is selected based on the political convenience rather than skill/capability to understand and manage IR. Mr. Prabhu could contribute to IR as he is professionally well qualified (CA), have rich experience, is sincere and dedicated towards his job. Many RMs just follow the advice of their secretaries.
* If the RM is changed, it will definitely be a big setback for IR.
