PECO Streamline N Gauge Code 55 - Universal Fine trackage system.Despite a low visible rail height of just 1.4mm, all brands of N Gauge model locomotives will run on this track.The ingenious rail section of PECO 55 combines strength and durability with a highly realistic appearance and uses the same universal rail joiners as Code 80: the geometry of this range has been cleverly designed to make it easy to build convenient, complex and aesthetically pleasing formations. These turnouts are constructed in our new versatile Unifrog design which can be operated, powered and switched like an Electrofrog or left unpowered if preferred.
