Designed for use with most Atlas and many other HO and N scale switches, ATL66 is an excellent choice for model railroaders who want cleaner-looking trackwork combined with additional electrical control capabilities.\u003c\/p\u003e\n\n\u003cp\u003eBecause the switch machine mounts \u003cstrong\u003eunderneath the layout\u003c\/strong\u003e, the operating mechanism remains out of sight instead of sitting alongside the track. This helps create a more realistic appearance around turnouts while still providing powered turnout operation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Makes the Deluxe Switch Machine Different?\u003c\/h3\u003e\n\n\u003cp\u003eThe major difference between the Atlas Deluxe Under-Table Switch Machine and a basic under-table switch machine is the Deluxe model's integrated \u003cstrong\u003edouble-pole, double-throw relay\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe DPDT relay provides two electrically switched circuits that operate in conjunction with the switch machine. This gives model railroaders additional options for controlling electrical functions associated with the position of the turnout.\u003c\/p\u003e\n\n\u003ch3\u003eBuilt-In DPDT Relay\u003c\/h3\u003e\n\n\u003cp\u003eATL66 includes a \u003cstrong\u003eDPDT relay with an actuating mechanism\u003c\/strong\u003e. DPDT stands for \u003cstrong\u003edouble-pole, double-throw\u003c\/strong\u003e, meaning the relay can switch two separate electrical circuits between two positions.\u003c\/p\u003e\n\n\u003cp\u003eOn a model railroad, this additional electrical switching capability can be useful when a secondary circuit needs to change state along with the turnout position. The exact wiring and application will depend on the layout's electrical and control system.\u003c\/p\u003e\n\n\u003ch3\u003eHidden Under-Table Installation\u003c\/h3\u003e\n\n\u003cp\u003eThe ATL66 switch machine installs \u003cstrong\u003ebeneath the layout surface\u003c\/strong\u003e, allowing the turnout above to operate without a large surface-mounted switch machine beside the track.\u003c\/p\u003e\n\n\u003cp\u003eKeeping the mechanism below the layout can significantly improve the appearance of visible trackwork, particularly around \u003cstrong\u003emainlines, passenger terminals, yards, industrial districts and heavily scenicked areas\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eCompatible with HO \u0026amp; N Scale Switches\u003c\/h3\u003e\n\n\u003cp\u003eAtlas specifies that the Deluxe Under-Table Switch Machine can be used with \u003cstrong\u003emost Atlas and many other HO and N scale switches\u003c\/strong\u003e. This makes ATL66 a versatile turnout-control component for model railroaders using a variety of track systems.\u003c\/p\u003e\n\n\u003cp\u003eWhen installing the machine with a specific turnout or non-Atlas track system, verify the turnout's mechanical requirements and installation arrangement before permanently mounting the switch machine.\u003c\/p\u003e\n\n\u003ch3\u003eAtlas Deluxe Under-Table Switch Machine Features\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003eModel railroad under-table switch machine\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eMounts beneath the layout\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eKeeps turnout operating hardware out of the visible scene\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBuilt-in double-pole, double-throw (DPDT) relay\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003eIncludes relay actuating mechanism\u003c\/li\u003e\n\u003cli\u003eProvides two electrically switched circuits\u003c\/li\u003e\n\u003cli\u003eUseful when additional electrical functions need to follow turnout position\u003c\/li\u003e\n\u003cli\u003eDesigned for use with most Atlas HO and N scale switches\u003c\/li\u003e\n\u003cli\u003eCompatible with many other HO and N scale switches\u003c\/li\u003e\n\u003cli\u003eBlack finish\u003c\/li\u003e\n\u003cli\u003eUseful for mainlines, yards, sidings, terminals and scenic trackwork\u003c\/li\u003e\n\u003cli\u003eAtlas manufacturer item number 0066\u003c\/li\u003e\n\u003cli\u003eFusion Scale Hobbies SKU ATL66\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eStandard vs. Deluxe Atlas Under-Table Switch Machine\u003c\/h3\u003e\n\n\u003cp\u003eFor model railroaders who simply need hidden turnout operation, a standard under-table switch machine provides a straightforward solution. The \u003cstrong\u003eDeluxe ATL66 adds an integrated DPDT relay\u003c\/strong\u003e, making it the more versatile choice when the turnout position also needs to control additional electrical functions.\u003c\/p\u003e\n\n\u003cp\u003eIf those additional contacts are not required, the standard under-table switch machine may be sufficient. When additional electrical switching is part of the layout design, the Deluxe model provides that capability in the same turnout-control installation.\u003c\/p\u003e\n\n\u003ch3\u003eUseful for Advanced Layout Wiring\u003c\/h3\u003e\n\n\u003cp\u003eThe built-in relay makes ATL66 particularly useful on layouts where turnout position is incorporated into the electrical control system. Because the relay provides two switched circuits, it offers considerably more flexibility than a switch machine designed only to move the turnout points.\u003c\/p\u003e\n\n\u003cp\u003eThe exact use of those contacts should be determined by the modeler's wiring plan and the requirements of the connected equipment.\u003c\/p\u003e\n\n\u003ch3\u003ePlan Installation Before Ballasting\u003c\/h3\u003e\n\n\u003cp\u003eBecause ATL66 mounts beneath the layout and mechanically operates the turnout above it, plan the installation while laying track whenever possible. Make sure there is adequate clearance beneath the turnout and that the switch machine can be properly aligned with the turnout's operating mechanism.\u003c\/p\u003e\n\n\u003cp\u003eTest the turnout through both routes and verify proper switch-machine and relay operation before permanently securing, ballasting or finishing the surrounding trackwork.\u003c\/p\u003e\n\n\u003ch3\u003eShop Atlas HO Switch Machines\u003c\/h3\u003e\n\n\u003cp\u003eBrowse our \u003ca href=\"\/collections\/atlas-ho-switch-machines\"\u003e\u003cstrong\u003eAtlas HO Switch Machines\u003c\/strong\u003e\u003c\/a\u003e collection for manual, remote, standard under-table and Deluxe under-table turnout-control components.\u003c\/p\u003e\n\n\u003cp\u003eFor complete track switches, browse our \u003ca href=\"\/collections\/atlas-ho-code-100-turnouts-switches\"\u003e\u003cstrong\u003eAtlas HO Code 100 Turnouts \u0026amp; Switches\u003c\/strong\u003e\u003c\/a\u003e collection.\u003c\/p\u003e\n\n\u003ch3\u003eBuild with Atlas HO Track\u003c\/h3\u003e\n\n\u003cp\u003eExplore our complete \u003ca href=\"\/collections\/atlas-ho-scale-track\"\u003e\u003cstrong\u003eAtlas HO Scale Track\u003c\/strong\u003e\u003c\/a\u003e collection for track, turnouts and layout-building components, including \u003ca href=\"\/collections\/atlas-ho-code-100-track\"\u003e\u003cstrong\u003eAtlas HO Code 100 Track\u003c\/strong\u003e\u003c\/a\u003e for flex track, sectional track, crossings and switches.\u003c\/p\u003e\n\n\u003cp\u003eFor rail joiners, terminal connections, track nails and other installation supplies, browse our \u003ca href=\"\/collections\/atlas-ho-track-accessories\"\u003e\u003cstrong\u003eAtlas HO Track Accessories\u003c\/strong\u003e\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eAtlas N Scale Track\u003c\/h3\u003e\n\n\u003cp\u003eBecause ATL66 is also designed for use with compatible N scale switches, browse our \u003ca href=\"\/collections\/atlas-n-scale-track\"\u003e\u003cstrong\u003eAtlas N Scale Track\u003c\/strong\u003e\u003c\/a\u003e collection for N scale track, turnouts and related layout components.\u003c\/p\u003e\n\n\u003ch3\u003eShop Model Railroad Track \u0026amp; Accessories\u003c\/h3\u003e\n\n\u003cp\u003eBrowse our complete \u003ca href=\"\/collections\/model-railroad-track\"\u003e\u003cstrong\u003eModel Railroad Track\u003c\/strong\u003e\u003c\/a\u003e selection for track systems, turnouts, switch machines and layout-building components in multiple scales.\u003c\/p\u003e\n\n\u003cp\u003eShop additional products from \u003ca href=\"\/collections\/atlas-model-railroad\"\u003e\u003cstrong\u003eAtlas Model Railroad\u003c\/strong\u003e\u003c\/a\u003e and browse \u003ca href=\"\/collections\/atlas-in-stock-products\"\u003e\u003cstrong\u003eAtlas In-Stock Products\u003c\/strong\u003e\u003c\/a\u003e.\u003c\/p\u003e","brand":"Atlas","offers":[{"title":"Default Title","offer_id":42099583648000,"sku":"ATL66","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0613\/6453\/5552\/files\/ATL66_FSH.gif?v=1789158245","url":"https:\/\/fusionscalehobbies.com\/products\/atl66","provider":"Fusion Scale Hobbies","version":"1.0","type":"link"}
