It’s a bold title. Railways won’t simply fix the future of transport, declares Gareth Dennis, they’re going to fix the future. Full stop.

A writer and lecturer who contributed to New Internationalist’s Big Story on railways (NI 539), the author is better known to many as the engineer who was sacked after Britain’s rail minister, Peter Hendy, complained about him speaking out over problems of overcrowding at London’s Euston station. For anyone who has ever been caught on the heaving concourse on a Friday night – passengers braced like sprinters on a starting block – it’s obvious that Dennis was right to raise safety concerns. So it was with confidence in his voice that I approached Dennis’s debut, a 267-page treatise that examines railways and their potential to fix a society in desperate need of change.
