Description
The Atlas 537 is an HO Code 83 Snap Track 22-inch radius 1/3 section curved track, four-pack — 10° arcs at the wider 22" radius, for fine curve trimming on the larger mainline radius.
Where to use it. Three 537s equal one full 22" curve section; one 537 paired with a half section (when available) gives you a 25° arc. The classic use case is matching the diverging leg of a 22" Custom Line or Snap-Switch turnout (Atlas 482/483/544) into an existing 22" mainline curve — the turnout's curved leg includes a partial radius, and a 537 brings the geometry up to a clean total.
Construction. Code 83 nickel-silver rail on brown molded ties with #2540 nail holes. Pre-fitted joiners, NMRA-compliant railhead.
