Its tighter geometry allows the diverging route to separate from the straight route more quickly than a #6 or #8 turnout, helping modelers fit additional switching and track capacity into a given area.\u003c\/p\u003e\n\n\u003cp\u003eThis makes ATL561 particularly useful for \u003cstrong\u003eyard ladders, industrial districts, locomotive facilities, storage tracks and compact switching layouts\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe tradeoff is tighter diverging geometry. Model railroaders operating long-wheelbase locomotives or longer rolling stock should consider the operating requirements of their equipment when choosing between #4, #6 and broader turnout sizes.\u003c\/p\u003e\n\n\u003ch3\u003e#4 vs. #6 Turnouts\u003c\/h3\u003e\n\n\u003cp\u003eThe biggest practical difference between a \u003cstrong\u003e#4 and #6 turnout\u003c\/strong\u003e is how quickly the diverging route moves away from the straight route. A #4 turnout provides more compact geometry, while a #6 provides a more gradual route through the switch.\u003c\/p\u003e\n\n\u003cp\u003eFor compact yards and industrial switching, the #4 can save valuable layout space. For mainlines, passing sidings, crossovers and areas regularly handling longer equipment, the broader #6 geometry may be preferable.\u003c\/p\u003e\n\n\u003ch3\u003eCustom-Line vs. Snap-Switch\u003c\/h3\u003e\n\n\u003cp\u003eATL561 is a \u003cstrong\u003enumbered Custom-Line turnout\u003c\/strong\u003e and should not be confused with an Atlas Snap-Switch.
