I'm starting a new project this year for the 80 year old Northern Pacific A-2 4-8-4. I'd like tips and tricks to build this engine. the main reason why i wanted to start this project is to build the Northern Pacific 4-8-4 series (A, A-1, A-2, A-3{SP&S 700}, A-4 and A-5). here are images of the Real and HO scale model of the A-2.
