Six pieces of 13.75″ radius Code 55 curve — a full curve section in Atlas’s smooth, prototype-look Code 55 system. 13.75″ is a comfortable medium radius for general-purpose mainline running.
Sold in a 6-pack of Full Curve sections at 13.75″ radius. Atlas Code 55 is the prototypically scaled N-scale track system, with .055″ tall nickel-silver rail set in brown ties for a far more realistic appearance than Code 80. All rail joiners are concealed within the tie strip, giving smooth, hidden transitions between sections. Compatible with all modern N-scale equipment (Atlas, Kato, MicroTrains, current Bachmann, etc.); some older deep-flange stock may bind on Code 55 — check wheels first.
How to use
Use as the 13.75″ radius arc in your mainline curve — combine 6 Full Curves to make a 67.5° quarter-circle, or 32 to make a full loop.
Half Curves at the same radius are the matching fitter — drop one in to make non-standard angles.
Joins to any Atlas Code 55 piece with concealed rail joiners.
Minimum rolling-stock compatibility: most modern N equipment runs fine on 13.75″ radius; longer 6-axle locos and 89′ flats prefer the larger radii (15″+).
Mix with shorter Half Curves of the same radius for fine geometry; transition to Code 80 with Atlas Code 55-to-80 transition joiners (2538).
