My main interest is Midland Railway locomotives so I am interested in the various volumes about the subject written by Bob Essery and Stephen Summerson. I will likely end up buying both sets of volumes but for now (since I have not seen either yet) I would appreciate feed back from members about the relative merits of the two series. Since it will of necessity be a gradual process of purchase, which do you think is the better author to go with initially - Essery or Summerson - or are there other books I am not aware of yet?
cheers
