The "HO Unitrak Railway Set Series" is now available, which makes it easy for beginners to realize an "easy-to-understand" and "easy-to-buy" layout plan! Curved line R550 - 22.5°×16. Batteries are not used even when running, emitting light, or lighting up.
Kato Unitrack in both N and H0 are extremely robust and easy to use. It lasts for years. I have used many different brands of track. Kato Unitrack is my favorite.
