I am considering building a short backyard mini railway and of course I need a loco. The XP class loco has always interested me and I remember riding the candy liveried XPT at the Heritage Park Railway in Lismore with my son. So this loco was the perfect candidate. Anyway I was wondering, if indeed I do decide I want to proceed with this idea, how do I build it? Metal or aluminium seems to be the best option for the body, but how do I make it follow the architecture and have the detail of the XP class? I am new to this sort of thing so please forgive me if I don't know anything.
Any help would be greatly appreciated
