More than 20 years ago, I left my fast life in London for a rather more relaxed one in Brighton and Hove. I never dreamt I could enjoy it more till all the business with the trains started up a few years back. The chaos at Southern Railway — which has seen commuters lose their livelihoods and property prices all along the London–Brighton line plunge, and culminated last summer in the resignation of the rail minister Claire Perry — has effectively put an end to the one thing I disliked about my seaside city.
