Rivarossi 4-8-8-4 Big Boy

Track Radius Needed For Rivarossi 4-8-8-4 Big Boy

Ryan asks:

“I’m re-configuring my HO layout and have recently acquired a 40-year-old Big Boy loco to pull several tank cars, boxcars, etc and navigate curves without issues. I was thinking 18″ radius curves but on second thoughts am inclined to try and accommodate 22″ curves instead. Input from anyone with experience would be great. Thanks very much.”
