New Delhi: The central government has given formal approval for renaming Mhow railway station in Madhya Pradesh's Indore district after B.R. Ambedkar, the prime architect of the Indian Constitution, officials said on Monday. Ambedkar was born at Mhow on April 14, 1891. According to official sources here, the Union Home ministry has requested the Madhya Pradesh government to issue a Gazette notification in this regard. Sources also said that Union Social Justice and Empowerment Minister Thawar Chand Gehlot had written to Home Minister Rajnath Singh and Railway Minister Suresh Prabhu on the issue. Renamed as Dr Ambedkar Nagar in 2003, the tiny township of Mhow, famous for pleasant climate almost throughout the year, is located 23 km from Indore and is essentially a cantonment area. The Indian Army also runs a College of Combat for training its officers at Mhow.
