My scale 2-8-0 runs fine on S Trax 25" radius. Couple of notes:
1. S Trax 25" radius is actually 24" when measured to the centerline as opposed to the outer rail. 2. At least on my engine, the pilot truck is very lightly sprung and prone to derail on track imperfections, otherwise it runs full DCC speed with no problem. Paul Tenney
