How do Europe's different rail gauges affect logistics, and is track gauge Britain's main limitation?
Short answerGauge changes create transfer problems, but loading limits and constrained infrastructure are often the more important barriers to heavy and resilient transport.
NotesMost of Europe uses standard gauge, while Ukraine and Russia use a broader standard and the Iberian Peninsula and Ireland use other gauges. A gauge break forces passengers and freight to transfer or requires adaptable rolling stock. Gauge alone, however, does not set capacity: axle load, speed, platforms, bridges, and tunnels determine what the route can carry. Spare routes also matter because a network with no redundancy cannot close a principal line for modernization without disrupting the traffic the upgrade is meant to improve.
