Questions about plastic rail from a newbie

[Ucwepn]

I made the Scotsman and the BR tank among others The GWR King smoke box door is a great fit on most engines, I paint them using humbrol enamel or acrylic. You could go a bit mad like myself and purchase some of the handrails off ebay too haha. I have pinched many an idea from HO/OO model railways.
