RailwayA 490 km railway connection to a deepwater port is required to exploit these ore deposits efficiently. Several routes were planned using Quantm software. The railway will start at an elevation of about 650m at the mine, proceed along a fairly level alignment for 350km, drops steeply for 100 km down to the coastal plain, then traverses that plain for 50 km to the port.[1][2] The gradients generally favour loaded trains.

In September 2010, Sundance Resources signed a memorandum of understanding with CRCC China-Africa Construction Ltd, which outlined construction plans for a 490 km railway linking the planned iron ore mines to a proposed port near Lolab.[3] Another Chinese company, China Harbour Engineering Co Ltd (CHEC), will build the port.

[edit] TrafficThe new railway is expected to carry 35 million tonnes of ore per year for 25 years. [4]

Old article I found but interesting about the elevation and loaded trains. And the 25 yrs
