This varies with the radius of the track and the nature of the equipment. Tubular track comes in 31, 42, 54, 72, 96, and 120" circles and maybe more. Scale equipment (like a scale bigboy) swings way out on smaller radius track. Longer passenger cars overhang the inside of the curve. Smaller equipment like O27 engines and short cars are less of a problem. What radius track are you using and what type of equipment are you running?
