In a new op-ed for Complete Colorado, Randal O’Toole argues that governments that run transportation systems should build rapid-bus lines rather than rail lines. Rail is expensive, and rail lines serve only particular routes. He concludes, “Transit agencies that want to build-light rail are wasting their taxpayers’ money. Cities that haven’t yet built light-rail should plan rapid-buses instead. Cities that have light rail should expand their systems with rapid buses and plan to replace the rail lines when they wear out with more efficient buses.” Someday I hope to write an in-depth essay about the history and theory of government-run transportation systems and their free-market alternative.
