The counterfactual railway system was constructed using nine heuristic principles. The most important was the Steiner Principle, which asserts that under certain conditions an optimal railway network is linked up by a set of spatially symmetric three-way hubs. The counterfactual network equals or exceeds the performance of the actual network according to various metrics. The counterfactual network achieves this performance with 13,000 route miles as compared to the 20,000 route miles of the actual system.

Keywords:   railway, counterfactual, heuristic, Steiner Principle, metric, hub, symmetry
