Weathering for Railway Modellers

I added this to my digital library yesterday and have been skimming through it today for weathering ideas. It is a very well illustrated and comprehensive guide to a wide variety of weathering techniques, both for rolling stock and locomotives. 

I'm itching to have a go now, using some of the washing and drybrushing methods that I've used for military modelling, with the specific approaches suggested in this excellent book. I was particularly impressed by the weathering of N gauge wagons, which was very effective even in such a small scale.

A bit pricey but definitely worth every penny.
