This is a single section of MTH 40-1057 RealTrax O-54 Curved Track. Assembling 12 sections together, will make a full 54 Diameter circle. Realtrax is simply the easiest O Gauge track system ever manufactured. Featuring solid metal rails strong enough to stand on and a built-in roadbed for a realistic appearance ensures that a RealTrax layout will last for years while sporting a realistic appearance not found in other O Gauge track systems. RealTrax incorporates built-in track bed joiners and long-lasting sprung- metal electrical connectors that make assembling RealTrax literally a snap. Because the roadbed is solid, RealTrax is perfect for temporary carpet based layouts. The built-in roadbed prevents any dirt from staining your carpet and it comes apart so easily that your temporary layout can be disassembled in minutes. While the RealTrax system employs solid nickel-silver rails that won't rust or oxidise in an outdoor environment, the plastic roadbed and rail ties are constructed of ABS plastic that can be compromised outdoors. Essentially, ABS plastic is not designed to withstand extreme temperature swings and can distort (in high heat) or crack in extreme cold. In addition, the plastic will tend to fade in colour since it has not been treated with UV resistant paint. As a result, we do not recommend that RealTrax be used outdoors.The Trainz SKU for this item is P11415150.Condition: NewTCA Grade: C-10Original Box: YesManufacturer: MTHModel Number: 40-1057Scale/Era: O ModernModel Type: Track/Switches/Etc.The Manufacturer's Suggested Retail Price (M.S.R.P) for this item is $4.99.
