Under the final proposal, the former Hung Hom Freight Yard adjacent to Hung Hom station will be converted into stabling sidings for Sha Tin to Central Link trains, and new access tracks will be constructed to link the Sha Tin to Central Link with the former Hung Hom Freight Yard. Central South station was excluded in the modified plan, as no suitable sites had been found. One station at Hin Keng (just south of Tai Wai) was added to the proposal afterwards, to alleviate congestion at Tai Wai station.
The MTRC announced a revised proposal on 11 March 2008. The government would fund all of the required  for construction. The Executive Council approved the construction cost of HK$79.8 billion in March 2012 and construction began on 22 June 2012.
