This is a well laid out book, with excellent photos. Sadly some of the written information is inaccurate. 3 examples. Newton Abbot 158/HST collision--implied driver SPADed signal, wrong- permissive movement and 158 driver misjudged his speed approaching HST in platform.
Fairwood Jn-- Class 50 loco derailed due to attempting to set back through points.
Whatley Branch (Frome)-- Not runaway, but derailment due to poor track quality, track at that location maintained by Mendip Rail. these are three that i have close knowledge of so can pick up errors. However, i expect that there are others. Not what you would expect from a book price as this one is.
