I know you did,t really want to hear from existing volunteers but I have been involved with both sides of the hobby and it does have its advantages. I first started out with modelling by joining my local club in Nottingham and went on to help build Deepcar and Carstairs, this was on tuesday nights.On saturdays and wednesday nights I used to go to Swanwick and helped with the restoration of Deltic 15. While there I was asked to train to be a second man on our loco, which then led to riding on several different classes as well. The point is that I was able to check out all these locos at close quarters for free so that when I came to start modelling in O gauge I was able to measure them in great detail. I know I am very lucky to have an understanding wife , but I think she is glad to have saturdays to herself whist I am at Barrow Hill still working on those pesky Deltics. These two sides of the hobby do have the advantage of travelling all over the country exhibiting at exhibitions with layouts and also supporting locos at preserved railways. So my advise is get involved if you can, both sides of the hobby can be great fun.
