Indore --- During 1870s, a Metre gauge line of Holkar State Railway was sanctioned between Khandwa and Indore passing the Mhow Ghat following a loan of £ 10 million sterling by Maharajah Holkar of Indore. The Holkar Railway required very heavy works due to very steep gradients(up to 1 in 40) on the Vindhya Ghats. It also involved digging of 4 tunnels aggregating 510 yards in length, deep cuttings and heavy retaining walls. River Narmada was crossed by a brigde of 14 spans, 197 feet each and piers 80 feet above low water level. There are 14 other large bridges with high piers, the highest pier being 152 feet above the bottom of the ravine. The first section Khandwa-Sanawad was opened for traffic in Dec 1874. The Narmada Bridge was opened for traffic on 5th Oct 1876. The Indore-Ujjain branch line was opened in August 1876 and the line was completed in 1880 following a loan of Rs. 7.5 million granted by Maharaja Jayajirao Scindia of Gwalior. The Holkar Railway and Scindia Neemuch Railway amalgamated under a single management in the year 1882 and were named as Rajputana Malwa Railway (RMR). In 1882, Khandwa-Indore line extended to Ajmer. The identity of Rajputana Malwa Railway remained for a very short while and its management was taken over by Bombay, Baroda and Central India Railway Company (BB&CI) on 1st January 1885. Indore Railway Station was reconstructed by BB&CI in the year 1921. The station have 6 plaforms with a total of 40 originating/terminating passenger trains. Station code - INDB.
