This extension is scheduled for completion in 2021 and will include the first cross-harbour rail tunnel to be owned by KCRC and the first KCRC-owned stations on Hong Kong Island. As part of its construction, the entire East Rail line's signalling system will be further upgraded to a communications-based train control (CBTC) system, similar to that on the West Rail and Ma On Shan lines, and in December 2012 a HK$850 million contract was awarded to Siemens for the installation of its Trainguard MT CBTC system, which will replace the existing TBL and ATP/ATO systems (although AWS will remain in use by intercity through trains). New Hyundai Rotem EMUs were ordered at a cost of HK$4 billion and will enter service in 2019, in advance of the signal upgrades, which are expected to be completed by 2020. However, due to the scandal at Hung Hom Station extension and damaged station facilities by revolutionaries, the target date of Hung Hom to Admiralty Section is possibly delayed to the first quarter of 2022. The proposed Northern Link will connect Kam Sheung Road station to Lok Ma Chau station by 2023. An infill station, Science Park station, has been proposed to serve the Hong Kong Science Park.
