Hi all, newbie here, currently involved in a 4X8 layout for N scale which is nearing completion, down to buildings, etc. I have a question (actually quite a few before it is done).....I have a N&W J 4-8-4 that is my favorite. The front 4 and back 4 are "floaters" on springs and they have a tendancy to jump track when going over turnouts. Anyone experience this before or have solutions? The N&W is my favorite so I would like to run it instead of just having it idle on the layout. (Currently have Robert West doing one of his great portraits for me of the N&W at Natural Tunnel in Va.) Thanks!
