Although our HO Code 83 track is perfect for modeling American main lines, this new Code 70 track is perfect for secondary lines, light branches, siding, etc. In fact, it will be perfect for modeling the railway of the early to mid 20th century when lighter railway was more commonly used. With precise details, correctly proportioned loops (leepers) and nickel silver rail, this new flexible track has been produced to the same high standard that modellers have come to expect from PECO and confirms the specifications set by the NMRA..
