The trains of Kowloon-Canton Railway Corporation (KCRC) are being driven by a new engineer. In December 2007 the government of Hong Kong, which owns KCRC, combined the company's rail operations with those of commuter rail operator MTR, which also is controlled by the government. Before its operations were merged with MTR's, KCRC provided commuter rail service in the Hong Kong region over three main lines. Its network consisted of some 113 kilometers (70 miles) of track. Although MTR runs the combined system, KCRC retains ownership of its rail-related assets and receives payments from MTR under a 50-year contract, which may be extended.
