The discovery of some embarrassing mistakes in her recent Rail Budget speech is learnt to have earned several officials the ire of Railway Minister Mamata Banerjee. In her speech,Mamata announced that two stations on the Kolkata Metro network — Rash Behari and Park Circus — would be renamed after Bhagat Singh and Mother Teresa,respectively. Much to the embarrassment of the Railway Ministry,it was later pointed out that there was no station on the Kolkata Metro by the name Rash Behari,and that the Park Circus station the minister referred to was actually the Park Street station. It was later understood that Kalighat station,which is located on the Rash Behari Avenue crossing,was incorrectly referred to as the Rash Behari station. Worried officials at the Kolkata Metro swung into action immediately,sending out clarifications that there was no proposal to rename the Kalighat station,which draws its name from a famous Kali temple. In damage control mode,officials in Delhi too clarified that there was no move to rename the Kalighat station. The mercurial Didi was sure not amused by the goof-up and Railway Ministry mandarins are on tenterhooks over what could follow.
