Oh, dear. Adrian Vaughan, railway historian extraordinaire, has obviously rushed this one out in a hurry. If not exactly under-researched, certainly a bit patchy. Curious choice of accidents to detail as well, many minor ones seem to be here for little more than comic relief and there are some big omissions. Plus which, Vaughan was a signalman and that's where you'd think his expertese would be, rather than telling us about, for example, the Kings Cross Fire. So not really in keeping with his fine tradition of highly readable railway histories. A rush job, and it shows.
