I really wanted to like this book. It had been bothering me that, as far as I could tell, no one had written a book on the history of BART---a fact that surprised me, given that I would expect San Francisco to have plenty of railfans---and I was really excited to see that someone finally had.
Sadly, though, it was a disappointment. Healy was BART's head of Media and Public Affairs for thirty-two years, and his writing style shows it. The book feels more like a collection of annecdotes you'd write up for the press than an actual, in-depth history. That alone might be excusable.
Worse, it has no notes or bibliography: Healy doesn't give readers any clues about the sources of the facts he reports. Are they from BART archives he has access to? Old newspaper articles? His personal memory? The fact that the acknowledgements page mostly lists people who he says told him "anecdotes" is certainly not encouraging. In any case, the lack of bibliographic notes means that even if he does have reliable sources for his information, there is no way for a reader to track them down to verify them and learn more.
Furthermore, the book does not seem to have been well-edited. I caught a couple of obvious factual errors (he refers to BART's gauge as narrower than standard gauge, rather than wider than it, for example), but I have no idea how many other typos or factual errors may have slipped through that I didn't catch. The publisher, Heyday, describes themselves as "an independent, non-profit publisher", and I'm guessing that their budget is fairly limited and didn't include any sort of technical editing.
I did manage to finish the book, which is why it got two stars rather than one, and it was at least a source of topics I might want to look into elsewhere. However, it certainly wasn't something I felt I could consider a reliable source on the history of BART.
