Many of the commission's other recommendations, including the abandonment of the Fort Nelson line, and discontinuation of uneconomic operations such as passenger services, were not followed. In the early 1980s the railway built a new line and acquired another. The Tumbler Ridge Subdivision, a electrified branch line, opened in 1983 to the Quintette and Bullmoose mines, two coal mines northeast of Prince George that produced coal for Japan. It has the lowest crossing of the Rocky Mountains by a railway, at . There are two large tunnels under the mountains: The Table Tunnel, long, and the Wolverine Tunnel, long. Electrified owing to the long tunnels and close proximity to the W. A. C. Bennett Dam and transmission lines, it was one of the few electrified freight lines in North America. Although initially profitable, the traffic on the line was never as high as initially predicted, and by the 1990s was under one train per day. The railway had incurred much debt building the branch line, and the expensive, unprofitable operations on the branch line could not help to repay that debt. In 1984 BC Rail acquired the British Columbia Harbours Board Railway, a line that connects three class I railways with Roberts Bank, an ocean terminal that handles coal shipments. Since the line had been constructed in 1969, it had been leased to the CPR, Burlington Northern Railroad, and Canadian National Railway in succession. 1990–2003 In the early 1990s, the provincial government reduced subsidies to BC Rail. As a result, BC Rail, burdened with several money-losing services that it was required to operate, saw its debtload grow more than sixfold between 1991 and 2001. In the 1990s, BC Rail branched out into shipping operations, acquiring terminal operator Vancouver Wharves in 1993 and Canadian Stevedoring and its subsidiary, Casco Terminals, in 1998. In 1999 these operations became the three operating divisions of a new entity, BCR Marine. BCR Group became the parent company of both BCR Marine and BC Rail. In early 2003, attempting to reduce the railway's large debt, BCR Group sold its BCR Marine assets except for Vancouver Wharves (which was also not included in the subsequent sale of BC Rail to Canadian National, and remains a provincial Crown corporation). On August 19, 2000, the Quintette mine closed, and the portion of the Tumbler Ridge Subdivision between Teck and Quintette, British Columbia, was abandoned. The last electric locomotives ran
