Question: Who publishes the best railroad history books today.
Answer: Signature Press
Hands down Signature Press has consistently published the very best books dealing with railroad history for quite some time. I admit I'm definitely bias but they consistently have the best page layout, best photo reproduction, best graphics and best topics of any railroad book publisher I know of today. Yes there are many other publishers devoted to railroad history but Signature Press always delivers the best. John Signor and his crew are definitely at the top of their game. Yes I realize their publications are somewhat pricey but you get what you pay for and, in the case of Signature Press, you definitely get quality for you money spent. And yes, I admit to having several Signature Press publications in my library. Their latest books 'Santa Fe Los Angeles Division' and 'SP Ten Coupled Locomotives' are to may way of thinking in a class by themselves - excellent research and presentation.
And no, I have no connection whatsoever with Signature Press - just an avid admirer.
