Unit service and maintenance cost increased sharply from 1982 although accounting for relative vehicle size mitigates this trend. The “average annual” rate of increase in real maintenance cost per bus-km from 1982 to 1997 was about 2.7 percent, or about 2.3 percent accounting for relative vehicle size.
The undertaking has not explained this unfavorable trend but has evidently brought it under control.
