Among other things I've been reading, I picked up a copy of "A West Coast Engineman" by Ian Tibbles..
Ian was a fireman on the west coast from 1962 to the end of steam in mid 1969. In this time he worked on every line on the coast. There's a good collection of photo's in the 250 odd pages. There's also the standard collection of character stories which quite honestly don't do much for me (now, a good chemical accident story, that's riveting reading). What is really usful is the descriptions of the various workings, as well as the shunting methods used at Westport and Greymouth. So an excellent resource for those with an interest.
