AF 336 Northern Help

Falcon70OGR Forum Member

Hello; just finished repairing a 336 AF Northern; runs and smokes fine; question: what is the best min radius or diameter to run this loco on? Using 20" radius fastrack for test and does OK but not happy. Is there a difference in rail height between AF track and Fastrak? Lastly, how to replace the front pilot truck spring? The one in there now is flat! Help and advise is much appreciated; Falcon70
