Add one more KR, and he is goin to spend more time to Delhi than Mumbai, but as much as everybody is aware of Mumbai Rly problems,except Mumbaikars themselves, similarly RM has to get the feel of Mumbaikars problem by setting his office in Mumbai.
Also, Mumbai is long been neglected since the time of Mr Ram Naik, he shd not be accused of bias unless he acts like Didi or Mr Yadav...
