The tension between policy stability and change is a key political phenomenon, but its dynamics have been little understood. Why Does Policy Change? examines and explains the dynamics of major policy change by looking at case studies from British Transport policy since 1945. The significant contrasts between road and rail policies in this period lend themselves perfectly to the authors' theories of what brings about policy turnabout.
