Siemens will supply its Trainguard MT automatic train protection (ATP) system along with automatic train operation (ATO), airlink radio transmission systems, and Sicas ECC-type electronic interlocking. In addition the line will be equipped for ETCS Level 1 operation for use by main line trains which will operate in conjunction with the automated mass rapid transit services.
The new line will branch from the Seoul - Incheon Line at Sosa and provide a direct connection with Wonsi New Port in Ansan. It will have a total of 13 stations and offer interchanges with Seoul metro Line 1 at Sosa, the proposed Ansan Line at Siheung City Hall, and Line 4 at Hwarang. The line is part of the new northern orbital around Seoul which is intended to reduce road traffic in the city.
Hyundai Information Technology is working as part of a consortium with Daewoo on the project which secured Won 1.52 trillion ($US 1.48bn) contract in 2011 and will manage and maintain the line for 20 years after it opens in mid-2016.
