L N E R 4-6-0 Tender Mixed Traffic Locomotives covers the design, construction, operation and performance of all 4-6-0 locomotives that ran on the London & North Eastern Railway between 1923 and 1947 and the LNER designed engines that ran on BR's Eastern Region until the end of BR steam in 1968. This includes the former Great Central 4-6-0s of classes B1 - B9 (the B1 and B2 later reclassified B18 & B19); the North Eastern Railway B13 - B16s; the Great Eastern B12s; and the LNER B17s, the Thompson B1s and rebuilds (B2 and B3/3).

The book has over 60,000 words and 350 black & white and color photographs, many previously unpublished from the archives of the Manchester Locomotive Society at Stockport. It will be of particular interest to railway modelers and enthusiasts of locomotive running and performance as well as those seeking more general locomotive history. The book is designed and written in the same style as David Maidment's previous Locomotive Portfolio books on engines of the Great Western and Southern Railways, and includes where possible his own experiences, seeing and traveling behind engines of these classes in the 1950s and early 1960s, especially the B1s, B12s and B17 'Sandringhams'.
