Communications 
transport. 
As regards railway communications, a glance at the map will show 
that the East Coast Section of the Bengal- 
Nagpur Railway passes right through the 
manganese area, the stations of Sigram, Chipu- 
rupalli, and Garividi, being most convenient. The output of Garbham, 
the Kodur mines, and Perapi is despatched from Garividi, from which 
the distance to the port of Vizagapatam is 56 miles. The projected 
railway from Raipur in the Central Provinces to Vizianagram will 
further improve the communications, especially for the Ramabhadra- 
puram deposits. The ores are at present carted from all the deposits 
to the railway, and the example of the Central Provinces in the 
construction of mining tramways has not been followed .
