I model preserved railways because I've worked on them. It was dirty, hard, hot and gruelling, and without a doubt some of the most enjoyable and fascinating experiences of my life, shared with some of the most engaging, erudite and entertaining people I have ever met. Why would I not want to recreate such beautiful vivid memories in some small way? Isn't that exactly what Tony Wright, Roy Jackson and countless others have done with such skill and artistry?
Oh, and sometimes it rained - I don't remember not turning up for duty when it did...
