Im currently building my first "from scratch" loco. An SD45 CSX (From what I can find, there was only one on the roster). The kit is an Athearn BB. Just wondering what method you guys use to install the rails and grab irons. For example, should I paint first, then glue, glue then paint or what..I preinstalled them just to insure they were all there and the problem I ran into was keeping the upright supports straight, so from what Im seeing they would have to be glued right?
