When it comes to making appointments to key posts,Railways Minister Mamata Banerjee does not hide her preference for people hailing from her home state of West Bengal. Having already filled up many Railway Ministry posts with Bengali officials,Mamata is now seeing to it that West Bengal cadre IPS officers get plum jobs during her term at the Centre. First,1981-batch officer Nazrul Islam was appointed as Executive Director Security in the Minister of Railways Cell. More recently,when it came to appointing the Chief Security Commissioners of the Railways Protection Force RPF in two zones,two West Bengal cadre IPS officers were handpicked. While 1982 batch officer R S Nalwa was appointed the CSC South Eastern Railways,1985-batch officer Sivaji Ghosh was posted as the CSC of Eastern Railways.
